/* Caption band — Figma "overlay" (component 7980:5793 / hover 7980:5792):
   - 88px tall, 130px on Hover (20px vertical padding) — same effect in both states;
   - fill: linear black 0% → 40%, top → bottom, over the WHOLE band (not masked);
   - effect: PROGRESSIVE background blur, radius 0 at 29% of the band height → 40 at the
     bottom (Figma radius 40 ≈ CSS blur(20px)).
   CSS has no progressive backdrop blur, so it is rebuilt from five stacked blur layers
   (1.25 / 2.5 / 5 / 10 / 20px), each masked to the band where Figma's radius passes that
   value: r(y) = 20px · (y − 29%) / 71%  →  1.25px @ 33.4%, 2.5 @ 37.9%, 5 @ 46.8%,
   10 @ 64.5%, 20 @ 100%. Positions are percentages, so the hover band scales with it. */
