/* ============ NAV (matches index.html) ============
 * Byte-for-byte port of the operator app's sticky mobile header
 * pattern in apps/web/src/shell/AppShell.tsx -- see the .nav block
 * in apps/marketing/index.html for the full rationale. Invariants:
 *   1. position: sticky (NOT fixed). Sticky stays in flow and avoids
 *      iOS Safari's fixed-element safe-area quirks.
 *   2. NO padding-top on the outer .nav. Padding lives on .nav-inner
 *      so the brand row clears the Dynamic Island while the sticky
 *      bg paints the entire row (including the safe-area strip).
 *   3. NO body { padding-top } reservation; sticky is in flow.
 *   4. Translucent rgba paper + backdrop-filter on every viewport.
