Adds constraint 4 (Lock the viewport) to app-bootstrap.md: the document head must carry the canonical viewport meta with user-scalable=no so native apps don't pinch-zoom or auto-zoom when an input is focused. Web browsers ignore the directive for accessibility, so one tag serves both platforms. Regenerates the AI discovery indexes (llms.txt, llms-full, agent-skills, capabilities). Companion to Fliplet/fliplet-studio#8626, which enforces the constraint via the viewport-not-locked rule in lintV3Boot. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

…s-refs, guarantee list - guarantee mapping is a numbered list instead of inline (1)-(4) prose - enforcement phrasing matches reality: the boot-HTML lint rejects the layout (rule viewport-not-locked); there is no deploy-time check - umbrella warning covers the lint-rejection failure mode - browser-behavior nuance (Android Chrome honors user-scalable=no) and the 16px input auto-zoom qualifier - fliplet-router.md, routing.md, frameworks/overview.md now say four boot constraints; indexes regenerated (also converges the one-run capabilities.md lag in llms-full.txt) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Summary
Documents the locked viewport as the fourth V3 boot HTML constraint in
docs/API/v3/app-bootstrap.md. On native devices a scalable viewport lets users pinch-zoom the app and makes iOS auto-zoom the page when an input field receives focus; V1/V2 apps were immune because the platform template hardcodesuser-scalable=no, but V3 boot HTML is AI-authored end to end, so the constraint must live in the doc the builder is required to fetch before writing any boot HTML.The canonical tag:
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no, viewport-fit=cover">. Web browsers ignoreuser-scalable=nofor accessibility, so the same tag is correct on every platform.Also regenerates the AI discovery indexes (
llms.txt,llms-full.txt,agent-skills,capabilities.md) — includes minor drift from a fliplet-router doc change that postdates the last regen.Companion PR
Fliplet/fliplet-studio#8626 enforces this constraint deterministically (
viewport-not-lockedrule inlintV3Boot, blockingupdate_screen_codedeploys). The lint's error message points the model at this doc — merge this PR first (or together) so the doc the AI is told to fetch actually documents the rule.Test plan
