🛠️ Key Changes & Technical Design Decisions

• Manifest V3 Core & Extension Icons (manifest.json, icons/):

  • Upgraded to MV3 with background service worker (background.js) and storage / tabs permissions.
  • Added dedicated extension icons (16px, 32px, 48px, 128px) generated from brand assets.

• Standalone Serverless Popup Studio (index.html, styles.css, script.js):

  • Re-architected with modular OOP domain classes: GitHubExtensionClient, StorageService, LanguageMasqueradeHelper, and ExtensionApp.
  • Supports 100% serverless commit authoring via GitHub Personal Access Token (PAT) or optional local/cloud Web Studio bridge.
  • Features date span presets, weekday commit steppers, Linguist Masquerade code generation, and inline progress with Pause / Resume / Stop & Keep controls.

• In-Page GitHub Profile Integration (content.js, content.css):

  • Injects a native-styled [ ⚡ ContraGit Studio ] button directly beside GitHub's "Contribution settings" on profile pages.
  • Automatically scans live .ContributionCalendar-day cells to compute active days, current streak, and trailing 30-day gaps.
  • Displays a glassmorphic flyout dock with 1-click deep linking into the full 52-week Visual Studio.
  • Resilient to GitHub client-side SPA navigation via turbo:load, pjax:end, and debounced MutationObserver.
