/**
 * style.css
 * -----------------------------------------------------------------------
 * Mobile-first layout skeleton. Positions and sizes every mount point
 * from index.html (loader, header, hero, floating nav, menu
 * container, modal root, footer, FAB). No animation states, no
 * JS-driven interaction styling — those arrive in later phases
 * (animations.css / Phase 7). Desktop-only overrides (e.g. floating nav
 * moving from bottom to top) belong in responsive.css, not here — this
 * file defines the mobile baseline per the "mobile-first throughout"
 * rule.
 *
 * Uses CSS logical properties exclusively (inline/block instead of
 * left/right/top/bottom-based sizing and spacing) so RTL/Arabic can be
 * added later via `dir="rtl"` with zero rebuild.
 * -----------------------------------------------------------------------
