/* ════════════════════════════════════════════════════════════════════════
 * BUNYAN — POLISH LAYER
 *
 * Mobile-fit, scroll progress bar, section ornaments, cinematic reveals.
 * Pure CSS — zero added JS. Total weight ~6 KB.
 *
 * Performance budget:
 *   - Only `opacity`, `transform`, `scale-x` are animated (compositor-only).
 *   - Scroll progress uses scroll-driven animations where supported,
 *     otherwise a fixed bar that doesn't update (graceful degradation).
 *   - Hamburger menu is `details/summary` (zero JS, native).
 *   - All section ornaments are SVG paths in CSS data-URI (no extra requests).
