# Refactor HeaderCanvas: ComponentManager, SCSS, and JSDoc

We refactored `apps/portal/view/HeaderCanvas.mjs` to improve code quality and documentation.

Changes:
- **Refactoring:** Replaced the nested `findButtons` helper with `ComponentManager.down(parent, 'button', false)` for cleaner, more robust component retrieval.
- **Styling:** Moved inline styles to a new SCSS file: `resources/scss/src/apps/portal/HeaderCanvas.scss` and applied the `portal-header-canvas` class.
- **Documentation:** Enhanced JSDoc for both `Portal.view.HeaderCanvas` and `Portal.canvas.HeaderCanvas` to clearly explain the App Worker <-> Shared Worker architecture and the "Luminous Flux" visual engine.
- **Cross-Referencing:** Added `@see` links to cross-reference the view and canvas components.
- **Cleanup:** Removed internal thought-process comments.

**Input from Gemini 3 Pro:**

> ✦ I have successfully refactored `HeaderCanvas` to use `ComponentManager.down()` for button retrieval, moved inline styles to `resources/scss/src/apps/portal/HeaderCanvas.scss`, and enhanced the documentation to clearly explain the App Worker <-> Shared Worker architecture. The changes are committed and pushed.
