/* tinyblue-persistent-flair.css — site-wide floating overlay styles.
 *
 * Loaded on every page (companion to tinyblue-persistent-flair.js). Owns
 * the look of the Dynamic Island (top-center transient), the Fleet
 * Pulse (bottom-left ambient), and the Cursor Glow. The homepage-only
 * hero atmosphere stays in tinyblue-flair.css.
 *
 * Apple alignment rules followed here:
 *   1. Each floating widget occupies a distinct corner zone so they
 *      never collide:
 *        top-center      → Dynamic Island
 *        bottom-left     → Fleet Pulse
 *        bottom-right    → chat bubble + network FAB (other modules)
 *        top-left/right  → brand + nav (other modules)
 *   2. Glass surfaces transition smoothly across theme changes
 *      (~240ms ease) — no hard color snaps.
 *   3. Every offset uses env(safe-area-inset-*) so notched/round-corner
 *      devices don't clip.
 *   4. Reduced-motion disables pip pulses and entrance transforms.
