/* BlueBark v7 — NO FRAME. Lockup sits directly on the forest background.
 *
 * v6 review: operator iPhone Safari + desktop review concluded the cream
 * frosted-glass frame, even tightened, still felt like a card-on-photo. The
 * brand mark should sit in the forest scene, not floating above it. v7 removes
 * the frame entirely and relies on:
 *   - hard-edged binary alpha extraction (delta=12 from cream #f5f4ee, plus a
 *     3x3 majority morphological filter to clean source edge speckle) so the
 *     lockup has zero cream halo at edges; partial-alpha = 0.00% (was 6.2% in v6)
 *   - dual drop-shadow filter on .hero__lockup for legibility against forest
 *     foliage variability: a tight dark shadow for crisp edges + a soft cream
 *     glow that compensates for the lost frame backdrop on light forest patches
 *
 * Asset chain:
 *   /assets/forest-bg-v4.jpg      (full-bleed forest, unchanged from v4)
 *   /assets/lockup-hard-v7.png    (binary-alpha extraction; 2813x1536; 0% partial)
 *
 * Math at standard viewports (lockup % of viewport area, no frame):
 *
 *   Viewport     | lockup w | lockup %       | constraint
 *   -------------|----------|----------------|------------
 *   1920x1080    |  640     | 33.3% width    |  ✓ (forest dominates above/below)
 *   1440x 900    |  640     | 44.4% width    |  ✓
 *   1024x 768    |  512     | 50.0% width    |  ✓

 *    375x 812    |  280     | 74.7% width    |  ✓ (mobile bp)
 *
 * Accessibility branches retained:
 *   - prefers-reduced-motion (unchanged)
 *   - prefers-contrast:more  (deepens forest-bg color and strengthens shadows)
