/* site-polish.css
 *
 * Global cohesive look + responsive polish for every WiSWR page.
 * Loaded AFTER each page's inline CSS, so it overrides safely.
 *
 * Goals:
 *   1) Unified typography (Apple system font / Segoe / PingFang) on all pages.
 *   2) Unified dark gradient background that does not break the Leaflet map.
 *   3) Unified sticky top nav with glassmorphism and orange active state.
 *   4) Touch-friendly tap targets, safe-area insets, no iOS zoom on focus.
 *   5) Horizontal-scroll nav on phones, no wrapping.
 *   6) Tables that don't overflow phone viewports.
 *
 * What we deliberately DO NOT touch:
 *   - The actual map canvas (#map, .leaflet-container) layout — only its z-index.
 *   - Chart canvases.
 *   - Existing widget colors except for the nav band.
