CODECAVE Design System

A complete, reusable design system extracted from first-party CODECAVE source — the CodeCavePro/brand repository and the production codecave.pro codebase. Every token, component rule, asset and font file in this package was read out of captured source, not inferred from a screenshot or a marketing page.

Link one stylesheet and the system is live:

<link rel="stylesheet" href="colors_and_type.css">

There is no build step, no package to install, no theme provider and no component bundle. colors_and_type.css declares the tokens on :root and ships a component class layer on top of them.

Product context

CODECAVE is a software delivery studio. The captured surface is its marketing and lead-generation site: a dark, high-contrast presentation whose entire job is to turn a visitor into one booked consultation.

Six services, and the site titles every one of them by the outcome it produces rather than the technology it uses:

Service Outcome line, verbatim
Cloud & DevOps Optimize costs. Protect your Data
E-Commerce Maximize revenue, dominate Markets
Autodesk plugins 10x efficiency with custom Plugins
Automation & AI Leverage virtual Workforce
HubSpot Aggregate data from all your Tools
AR & VR Stunning visualisations for your business

Production stack. Astro 7 + Vue 3 + Tailwind 4, GSAP 3.13 with ScrollTrigger, Lenis 1.3.11 smooth scroll, vue3-carousel, Strapi as the content backend. 61 .astro files, 45 .vue components, zero React, no Storybook. The Tailwind 4 @theme block in src/styles/global.css is the authoritative token source; the brand repository's src/tokens/*.css publish the same ramp independently.

Conversion shape. Exactly one primary action per page — a violet glow button reading "Get a free consultation" — supported by a consultation form that asks for one required field (e-mail) and treats everything else as optional. The voice is plain, specific and non-promotional: "Scope, milestones and outcomes upfront." / "We are ready to sign an NDA — your idea stays yours."

What defines the visual system (the long version is DESIGN.md):

  1. Depth without contrast. The page is #0A0A0B and a card is #0F0F15 — one hair apart. Separation comes from radius and a 1px #2B2848 border, never from a lighter fill.
  2. Enormous radii. 24px is the default card corner. Feature cards take 44px; section panels reach 64px, and 120px above 768px. Nothing in the system has a small corner.
  3. The inverted glow. Section panels cast violet light upward — every Y offset in --shadow-section is negative. It is physically wrong and instantly recognizable, and it is the single most important thing not to normalize.
  4. Violet is rationed. #5F20FE lives on edges, links and marks and never fills a large area. When a violet field is genuinely needed the system switches to #9980FF with #1B0D4E text — the only dark-on-light text anywhere in the system.

The context/ intake tree is not published in this repository. It is the capture workspace's raw evidence — full snapshots of the codecave.pro and brand-repo working trees — and the table above cites it so each claim stays traceable to where it was read, not because the folder ships here. The component sources are preserved in src/components/ instead, so the code behind the rules can be read without re-running intake: 38 files — every Vue component this system documents, with the helpers and icons they reach for. What is genuinely captured from elsewhere stays in src/captured/: the production global.css, the wordmark, and this repository's own earlier token CSS in src/captured/brand-repo-tokens/.

tokens/ is the one derived artefact rather than a copy: colors.ts, layout.ts and typography.ts mirror colors_and_type.css as typed modules for consumers that cannot read a stylesheet — design tooling, canvas renderers, PDF and email builders, native apps. The CSS remains the source of truth.

Three of the entries above are published, not stored, here. colors_and_type.css, tokens/ and fonts/ are authored under the repository's src/ and copied to these URLs by the build, so every link a consumer or a deliverable already has keeps working. tools/astro-passthrough.mjs holds the map and asserts the copy arrived; check:links and check:examples read the same map rather than restating it.

The components are not in here. They live at the repository root, in src/components/ (every component, helper and icon — edit there) and src/captured/ (the eight files captured from elsewhere — never edit). They moved out because docs/ is what the site publishes and they are not published: the specimens mount the COMPILED bundles under storybook/compiled/, and the package is built from the sources directly. src/logos/ holds the three vector masters the ramps above are rendered from.

There are two browsable surfaces, and they answer two different questions. kitchen-sink/ asks whether a part is right — a token, a specimen, a live component — and examples/ asks whether the parts compose into something a client receives. DESIGN.md and colors_and_type.css sit underneath both as the rules and their machine-readable half.

It used to be five: a brand page, preview/ for tokens, storybook/ for components, artifacts/ for compositions, and two separate indexes over them. The split was real but nobody navigating it could hold five surfaces in mind, so the brand page folded into the front door as anchors, preview/ and storybook/ merged into one kitchen sink, and artifacts/ became examples/. Route counts went from 30 to 34 — the surfaces collapsed, the content did not.

storybook/ is now inputs rather than a surface, which is worth knowing before looking for a page there. It holds the compiled bundles the specimens mount, their ports and their placeholders; the specimen PAGES live under pages/kitchen-sink/. The directory kept its name because every specimen identity — scoped style ids, __file — is derived from it, and renaming it would rewrite every data-v- attribute in every bundle for nothing.

logos/, icons/ and favicons/ are the rendered brand assets, and they are the only home each one has. They are output: tools/generate-brand-assets.sh renders all three from the vector masters in the repository's src/logos/, and they are tracked so a consumer can take a PNG without owning a rasteriser.

They used to exist three times over — at the repository root as the script's output, and again under build/ and assets/ as hand-made copies. The copies were byte-identical and nothing derived them, so a re-render updated one home and left the other two silently saying something else. 43 files were duplicated that way. build/ is gone; its two files that were not copies are logos/logo.svg (codecave.pro's header lockup, which this repository does not draw) and site.webmanifest, now served from the site root where its absolute icon paths resolve — they pointed at /icons/ and 404'd from the day it was captured.

imagery/source/ is the same contract for the decorative art — eight SVGs copied byte-for-byte out of codecave.pro/src/assets/images/. The seven files one level up in imagery/ are the presentation copies: identical artwork with a single #050505 ground rect added, because the originals are stroke-only on a transparent root and therefore do not render on a light canvas. Ship from imagery/source/; review from imagery/.

Group Files Source
Vectors logos/codecave-wide.svg, logos/codecave-tall.svg, logos/codecave.svg src/logos/, copied on render
Site marks logos/logo.svg codecave.pro production
Raster lockups logos/codecave-{wide,tall}-{size}-{finish}.png, logos/codecave-{size}x{size}.png (8 sizes × 4 finishes × 3 lockups) rendered from src/logos/
Icon ramp icons/16x16.png … icons/512x512.png (7 sizes) rendered from src/logos/codecave.svg
Web runtime favicons/favicon.ico, favicon.svg, favicon-96x96.png, apple-touch-icon.png, web-app-manifest-192x192.png, web-app-manifest-512x512.png, and site.webmanifest at the site root rendered from src/logos/codecave.svg

The production site's own public/favicon.svg is not shipped here. As captured, codecave.pro still serves the Astro starter's default favicon — a stock framework glyph, not a CODECAVE mark. It is left in the evidence snapshot (context/local-code/codecave.pro/files/public/favicon.svg) and deliberately kept out of the rendered ramps. Use favicons/favicon.svg, the real brand mark.

assets/ holds what is not rendered from a master: the UI icons, the checkbox tick, and the original font uploads. The lockups and app marks it used to duplicate now live once, in logos/.

Every lockup exists in eight sizes × four finishes. The brand repo's build.sh renders src/codecave.svg, src/codecave-wide.svg and src/codecave-tall.svg at 96/128/256/300/350/500/600/1024 into codecave-{wide|tall}-{size}-{text-white|text-black|all-white|all-black}.png. text-white is the default on dark; text-black is for genuinely light surfaces; the two all-* finishes are one-ink print. This package preserves a representative subset — regenerate any other size from the vectors rather than upscaling a PNG.

Fonts are real and bound. colors_and_type.css opens with six @font-face blocks pointing at ./fonts/Satoshi-*.woff2 with .woff fallbacks. Nothing is described in prose only.

Preview Manifest

Twelve cards, one concern each — the foundations half of the kitchen sink. Open kitchen-sink/index.html and work down from the Tokens and CSS components sections, or open any card directly. Every card links ../colors_and_type.css and renders live tokens, live components and real preserved files: there are no screenshots and no redrawn marks anywhere in the set.

Card What to inspect What it demonstrates
kitchen-sink/index.html The hub over both halves. Confirm every card and story opens, and that the lockup renders. logos/codecave.svg, .divider, .eyebrow
kitchen-sink/colors-primary.html That #5F20FE never fills a large area, and that cyan appears nowhere as a UI color. --color-action, --color-hovered, --color-glow-25, --gradient-brand, the 12-step brand ramp, the 13-step gray ramp, the single-use accents, the technology wash, the 4-step error ramp. Source: src/captured/styles/global.css, tokens/colors.css
kitchen-sink/colors-theme-dark.html Four surfaces one hair apart — check they still separate. Read the contrast ratios on the foreground ramp. --color-surface-primary/-secondary/-tertiary/-quaternary, --color-body-*, .card in situ
kitchen-sink/colors-theme-light.html The three light surfaces that legitimately exist, and why no light theme may be derived from them. gray-50 as ink vs. as a field, inverse lockup usage, error-100 rationale
kitchen-sink/typography-specimens.html Whether the six Satoshi cuts render distinctly. If they look identical, the @font-face binding is broken. fonts/Satoshi-*.woff2, the nine-step scale at true size, .eyebrow / .lead / .eyebrow-lead with a counter-example. Source: tokens/typography.css, homepage/expertise.astro
kitchen-sink/spacing-tokens.html The asymmetric section rhythm (200px above, 120px below) and bottom-heavy card padding. --gutter-*, --section-padding-top/-bottom, --card-padding, --control-height, --input-height. Source: tokens/layout.css
kitchen-sink/spacing-radius.html Eight radii at true size, the measured homepage census, and the same card at 4px and 0px for comparison. --radius-control → --radius-section-md, .card, live .section-container across the 768px breakpoint
kitchen-sink/spacing-shadows.html The space above the panel — that is where the violet has to appear. Then the conventional-shadow counter-example beside it. --shadow-section (three negative-Y layers), --shadow-glow-button, --shadow-input-focus, --shadow-input-error
kitchen-sink/components-buttons.html Rest, hover, active, focus and disabled shown together; tab through the focus row. .btn + -glow/-primary/-secondary/-tertiary/-ghost/-text/-link/:disabled, and the one sanctioned CTA pairing. Source: common/Button.vue, common/GlowButton.vue
kitchen-sink/components-inputs.html Click into the fields. The floating label must never collide with the value, and focus must be a halo rather than an outline. .field, .field.is-error, .error-message, label .required, .checkbox, .chip, radios, the assembled consultation form. Source: common/InputText.vue, TextField.vue, Checkbox.vue, Radio.vue, common/forms/ContactUsForm.vue
kitchen-sink/components-progress.html That the bar is violet at 15% and near-white only at 100%. If early progress reads near-white, the gradient is being sized to the fill instead of the track. .rule, .progress, .progress-value, .progress.is-indeterminate, --gradient-brand as a field, and three counter-examples: stretched full width, gradient sized to the fill, thickened to 16px. Source: the brand repository's previously published docs/index.html
kitchen-sink/brand-imagery.html Every plate must show visible strokes. A plate that reads as flat near-black means the #050505 ground rect is missing from that file, not that the art is subtle. The seven harvested section backgrounds on their required ground, the 0.8 / 0.65 / 0.55 / 0.45 opacity ladder that produces the falloff, the three gradient stops, and the two imagery-only literals recovered in the deep pass (#391398, #4C4759). Source: codecave.pro/src/assets/images/
kitchen-sink/brand-assets.html Every frame must contain artwork. An empty frame means a missing file, not a styling bug. Check the 16px icon still reads as a chevron. Real files from logos/, icons/ and favicons/ loaded via <img>, <object> and CSS url(...): both lockups, the chevron, all four raster finishes at 256px, the seven-step icons/ ramp at native size, the web runtime set (favicon.ico, apple-touch-icon.png, both PWA manifest icons), the production logo.svg, the 1024² app icon, and the six font specimens

These cards no longer sit on a surface of their own. kitchen-sink/index.html gathers them and the component stories below on one page, and the main menu carries the only other surface, examples/index.html.

Component Storybook

Thirteen components extracted from codecave.pro — twelve Vue islands and one Astro component. The components half of the same page: open kitchen-sink/index.html and read down to Live components.

The stories mount the real components: tools/build-storybook.mjs compiles each .vue source verbatim (vue/compiler-sfc + esbuild) into storybook/compiled/, and generates storybook/tw-bridge.css — the site's own Tailwind theme plus every utility the components use, scoped to the story canvases with a preflight equivalent. Pages render them with the vendored Vue and GSAP runtimes; no external network, no build step at view time. The one .astro component cannot run in a browser, so kitchen-sink/components.css survives only as its hand-translated port (.cc-chip). Where the storybook deviates from production — Strapi-hosted images swapped for local placeholders, positioning stages for absolutely-positioned cards — the gap is written on the story page rather than silently papered over.

Group Components
Primitives Button (7 variants), GlowButton, InputText, TextField, Checkbox (2×2), Radio (2 variants)
Content ArticlePreview, Review, TechnologyCard, ProjectChip, TypingEffect, PainPointsItem
Compositions LinkGroup

Each story page carries the real defineProps signature, a variant/state matrix rendered live, and a findings section. 54 findings are recorded — 28 flagged as defects, 26 as design observations. The ones that change runtime behavior:

  • --default-transition-duration is not the project's variable. Checkbox.vue:75 and Radio.vue:61 both use it in a transition shorthand. It appears nowhere in the project's own code — it resolves to 150ms from Tailwind's default theme, emitted because transition-colors is in use. Inside a Tailwind build the indicators ease; lift either component out and the shorthand collapses and they snap.
  • Button's isDisabled does not disable. It sets opacity and cursor only; the disabled attribute is never bound.
  • TextField syncs its model on change, not input — so v-model updates on blur while InputText in the same form updates per keystroke.

The storybook is static HTML and needs no build. It is not a Storybook (@storybook/*) install: codecave.pro is linked read-only, so nothing was written into that repo.

Email CTAs

examples/raw/email.html shipped its two CTAs as green buttons. The cause is a single attribute:

<td align="center" bgcolor="var(--brand-color-primary)">

bgcolor is a presentational attribute, parsed with the HTML legacy color rules — a fixed-width algorithm that has no access to CSS at all, so it cannot resolve a custom property. It does not fail and fall back; it substitutes 0 for every non-hex character and reads what is left as a color. For var(--brand-color-primary) that yields #A0D000, a lime green. The literal string is doing the choosing, not the token.

Both CTAs in email.html and both in newsletter.html are now the glow button, written with literals end to end:

Property Value Why a literal
bgcolor / background #9980FF The one violet field in the system.
color #1B0D4E The only dark-on-light text in the system — 5.67:1.
border-radius 9999px Pill, per the radius rules.
box-shadow 0 0 64px 0 #7A58FFA8, 0 0 16px 0 #4F22FFA6, 0 0 4px 2px #5B34FA The halo, verbatim from --shadow-glow-button.
padding / font-size 16px 32px / 18px Outlook's Word engine ignores var(); the button would collapse to zero padding.

Never use var() inside bgcolor, and prefer literals over tokens anywhere in an email artifact. Custom properties are unsupported in Outlook on Windows and unreliable elsewhere; the design system's token layer stops at the inbox boundary.

Known limits, not defects: Outlook squares the pill and drops the halo, leaving the flat #9980FF field with #1B0D4E text. That degradation is intentional — the fill and the text color are the parts that carry the brand.

Footer signature

The generator emits a placeholder postal address and the brand-guide host. The registered line, in both email artifacts, is:

CODECAVE · 8 The Green, STE B, 19901 Dover DE, US · codecave.pro

The other four artifacts — deck, landing, poster, form — name codecave.pro in their footers too. The generated files pointed every one of those at the brand-guide host instead; that host is not CODECAVE's website, so all six artifacts now carry the company address.

Reuse workflow

  1. Copy colors_and_type.css, fonts/ and favicons/ into the target project, keeping the relative layout — the stylesheet resolves fonts as ./fonts/Satoshi-*.woff2.
  2. Link it once, at the root of the document. The tokens land on :root and the baseline sets the page to #0A0A0B with #F4F4F6 text.
  3. Consume the semantic layer, never the raw ramp: --color-surface-*, --color-body-*, --color-heading, --color-action, --color-hovered. Exactly three raw values are legitimate — glow-25 (glow fill), shadow-0 (the upward glow) and progress-0 (the gradient mid). Never hard-code a hex.
  4. Use the component classes rather than re-deriving them: .btn + variant, .card, .card-article, .card-feature, .field, .checkbox, .chip, .eyebrow, .lead, .eyebrow-lead, .stat, .divider, .page-container, .section-container. These are the public API.
  5. Read DESIGN.md's Do's and Don'ts before shipping. The thirteen Don'ts are the fastest way to catch work that has drifted off-system — a downward shadow, a small radius, a second glow button, a purple wash, or a light theme.
  6. Check Known divergences. Two rules here intentionally differ from what codecave.pro ships today (error text contrast, real vs. synthesized font weights). Each is documented with the production value if you need to match live exactly. Buttons are not among them: the .btn* layer is a transcription of Button.vue and GlowButton.vue, down to the halo hex literals and the 150ms transition-colors — including the tertiary hover that darkens its border to #1B0D4E. The only addition is the :focus-visible ring, which production never implemented.
  7. Start from examples/ when building a whole surface rather than a control. Those six files show the system carrying real page density, which is where the 200/120 rhythm and the one-primary-action rule actually get tested.

Superseded setup output

guide.md and the former system/ tree are artefacts of the original /design-systems/create registration run, which read the palette from the brand site's README rather than from source. That palette was wrong — it mapped #aaccee to the page background and #5F20FE to body text; #aaccee appears in no first-party file, and #5F20FE is the action color and is never body text. DESIGN.md, under Colors → The 2026 palette rebuild, documents the correction in full.

brand.json was then corrected to the source-backed values (#5F20FE action, near-black canvas, near-white ink, 24px radius — re-seeded again after the 2026 palette rebuild) and the generator re-run against them. The seed is right; the generator's derivation is not. Feeding it #5F20FE produced a ten-step palette whose primary is #7040da, and the resulting token layer — system/variables*.css, system/tokens.*.json, system/theme.json, system/kit*.html and system/index.html — contained zero occurrences of #5F20FE. It also shipped a light theme, which this brand does not have. That layer has been removed rather than corrected: a second set of custom properties on a different primary is worse than none, because a consumer who links it gets a brand that is not CODECAVE and no error to tell them so.

What survived the removal is examples/, promoted to the top level and re-based on colors_and_type.css. brand.json and guide.md stay — both are on the real palette — though guide.md remains a short generated orientation note and lags this package in detail.

This package — colors_and_type.css, DESIGN.md, tokens/, preview/, storybook/, examples/ — is the source of truth.

Verifying the package

npm run build:storybook && npm run check

The build first, because check reads output as well as sources: the package's dist/, and the compiled storybook bundles that check:importmap resolves against the vendored runtime map. Then eight assertions — the package against its origin, the port adapters against their interfaces, the token layer against Tailwind's, the import map, the findings counts, the deliverables, and every cited documentation route.

Nothing here compares this repository to codecave.pro, and as of 2026-08-25 nothing tries. check:captures did, and was removed: the site installs this package and pins it with --frozen-lockfile, so it lags between releases by design. Components are developed here, tried in the storybook here, published, and the site bumps afterwards — a check demanding the two be equal was red for exactly the changes it existed to protect.

The reading that goes with it: a specimen on this site is a record of what this repository ships, which is what codecave.pro will get at its next bump, not necessarily what it renders today. Treat any claim of the form "production does X" about a component with that in mind.

Developing a component

Edit the .vue under src/components/ (or src/captured/, though nothing there is authored) and commit. There is no regeneration step. storybook/compiled/*.js and storybook/tw-bridge.css are generated and gitignored, on the same rule as packages/brand/dist/ and dist/.

To see the change, run npm run dev — the kitchen-sink specimens import the .vue sources through Vite and hot-reload, so the compiled bundles are not in that loop at all. They exist for ds-bundle/, whose Design-project cards cannot run a bundler; they are read where npm run build:storybook writes them.

npm run build:storybook builds the package first, because it compiles each specimen out of packages/brand/dist/src and cannot run without it.

This is a deletion, not a convenience. Until 2026-08-27 those thirteen files were committed and guarded by check-tw-bridge.mjs, which compared a sha256 of both component roots against a digest in the tw-bridge.css header — so editing a component and committing it failed the build until you regenerated. That guard existed only because the generator once needed a codecave.pro checkout and could not run everywhere. Once it could, the check was failing builds over files CI already rebuilt and replaced before publishing. It took the 2.4.1 release with it on the way out.

Ports — what a component depends on outside itself

A captured component sometimes imports something a static docs page cannot resolve the way production does. One does today: project/pain-points-item.vue sanitises its markdown with isomorphic-dompurify, whose job is to pair DOMPurify with jsdom so the call also works during SSR.

Those dependencies are inverted, not stubbed. storybook/ports/ports.d.ts declares the narrow interface the component actually needs; an adapter beside it implements that interface for a static build; the PORTS table in tools/build-storybook.mjs is the only place a specifier is wired to an adapter. Everything else still compiles from the real source.

An adapter substitutes the environment, never the behaviour. The sanitiser port really sanitises — it is plain dompurify at the version the isomorphic wrapper resolves to, minus the jsdom half that only matters on a server. The third story on the PainPointsItem page proves it rather than asserting it: hostile markdown goes in, and the verdict under it is generated after mount from the DOM the real component produced. It was an identity function for about a day in August 2026, which was wrong — it made that page the one place in the storybook where the component on screen was not the component in production, in exactly the behaviour anyone visits that page to check.

Where an adapter genuinely cannot reach production, the specimen says so on its face. No specimen needs that today: since CCWEB2-332 the CMS-shaped components resolve media through an injected resolveImage() that defaults to identity, so a fixture's /uploads/foo.png reaches the <img> unchanged and 404s on whatever origin serves the page. Every page therefore swaps in a local placeholder after mount — via storybook/placeholders.js, which knows that LazyImage reads data-src and that assigning .src to one of those loses a race with its IntersectionObserver.

The distinction is not vocabulary. A stub is unchecked — it fails as an undefined in someone's browser, at the one moment the specimen was supposed to be proving something. An adapter is typechecked against its interface, so it fails at build time instead:

npm run check:ports

which npm run check runs for you. The bar for adding a port is narrow, and ports.d.ts states it: if swapping the implementation would change what the specimen looks like, it is not a port — it belongs in the bundle.

The bar for keeping one is just as narrow, and it is the build that holds it. check:ports typechecks an adapter whether or not a specimen imports it, so a green check on its own can be coverage of nothing — which is what StrapiPort quietly became once the CMS-shaped components took an injected resolveImage() and stopped reaching for a Strapi base URL. Every build-storybook.mjs run therefore ends by naming the specimens each port stood in for:

SanitizerPort stood in for 1 specimen(s): project/pain-points-item.vue
