Free Layout Zone

These can support real layout and visual overhaul: - Home page - Login page - Register page - Recovery page - Contact/features/static pages - Loading/pre-loading states - Public page header/footer - Instance logo, hero, favicon, and Open Graph images

Possible changes: - New page composition and element placement - Background image or muted self-hosted video - Motion/animation with reduced-motion fallback - New logo/wordmark treatment - Custom text and static copy - Custom buttons, panels, footer links - Remove or suppress vanilla public marketing/donation elements

Theme And Shell Zone

These can be visually tuned, but should be approached carefully: - Drive - App launcher / creation screen - Settings/profile/support pages - Modals/dialogs - Sidebars - Top toolbars - App icons and color mapping

Possible changes: - Theme colors - Icons and app launcher presentation - Button states - Modal styling - Drive/sidebar visual density - Toolbar visual treatment - Whiteboard palette - Loading indicators

Constraints: - Prefer CSS/theme and documented AppConfig knobs. - Avoid moving DOM nodes that CryptPad JS expects to find by selector. - Verify every changed surface in a real browser.
