/* ============================================================
 * Mobile tap latency fix (2026-05-09).
 *
 * Without `touch-action: manipulation`, Chrome on Android in portrait
 * orientation treats the first tap on any control as a *potential*
 * double-tap-to-zoom gesture and waits ~300 ms for a second tap. The
 * delay is often invisible (event eventually fires), but in narrow
 * viewports near zoomable text it can swallow the first tap entirely
 * (user reported: hamburger does not open in portrait but works in
 * landscape).
 *
 * `touch-action: manipulation` tells the browser: panning + pinch-zoom
 * are still allowed, but disable double-tap-zoom for this element ─
 * fire `click` immediately. This is the recommended fix from web.dev:
 * https://web.dev/articles/mobile-touch
 *
 * `-webkit-tap-highlight-color: transparent` removes the flash of grey
 * iOS/Android paint over tapped controls (purely cosmetic).

 * Mobile bottom-sheet pattern for the navbar dropdown.

 * on a phone). Instead the menu slides up from the bottom of
 * the viewport like a native iOS / Android sheet, with a
 * dimmed backdrop, full-width tap targets and momentum scroll.
 *
 * Trade-off: not a perfect "native" sheet (no swipe-down to
 * dismiss yet) but closes the two reported bugs immediately:
 *   - portrait: full-width target, no overlap with URL bar
 *   - landscape: max-height + overflow-y so list always scrolls
 *
 * Backdrop is the .nav-menu-backdrop sibling div rendered by
 * MuseApp.setupNavbar(). Its tap closes the sheet.
