Move topbar outside the grid container as a standalone sticky header (Shopify/Stripe pattern). Sidebar and icon bar use position:sticky relative to topbar height. Mobile uses drawer pattern with backdrop, focus trap, ESC close, and scroll lock. Tenant branding moved from sidebar header into the topbar. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* Render-blocking boot script — runs synchronously before first paint.

*
|
|
* Intentionally a classic IIFE (not an ES module) so the browser executes it
|
|
* immediately while parsing <head>. This prevents layout flicker by applying
|
|
* persisted UI state (sidebar collapsed, contrast mode) before any content
|
|
* is rendered. Uses `var` for broadest compatibility in the sync path.
