Conversation
- Added a visually hidden "Skip to main content" link to `App.tsx` that appears only when focused via keyboard.
- Converted `ContentView` wrapper `div` to a `<main id="main-content">` tag to act as the skip link target.
- Added `tabIndex={-1}` and `focus:outline-none` to `<main>` to allow programmatic focus without showing an unsightly visual focus ring to mouse users.
- Logged a learning to `.jules/palette.md` regarding proper skip link focus management in React apps using Tailwind CSS.

💡 What
Added a "Skip to main content" link at the top of the application that allows keyboard and screen reader users to bypass the repetitive Effects Explorer sidebar navigation and jump straight to the active 3D visualization view.
🎯 Why
Without a skip link, users navigating via keyboard or assistive technologies must tab through every effect category and button in the sidebar before they can interact with the main content area (such as the 3D model controls or the upload button). This creates a frustrating and inefficient experience. The skip link dramatically reduces interaction friction for these users.
📸 Before/After
Before: Keyboard users load the page and press "Tab". Focus lands on the first item in the sidebar ("Cel Shading"). They must press "Tab" ~9 times to reach the main content area.
After: Keyboard users load the page and press "Tab". Focus lands on an immediately visible "Skip to main content" link. Pressing "Enter" instantly focuses the main content area, bypassing the entire sidebar. For mouse users, the UI remains completely unchanged (the link remains visually hidden).
♿ Accessibility
