   rotation/shape, no custom re-pointed variant (v2 rotated it to point straight down to match
   a reference image, but that broke from the CI rotation angle — reverted per user request).
   Reuses the exact same <img>+drop-shadow technique and `heroArrowGlow` keyframes as the
   desktop `.hero-arrow` for identical tone-and-manner — only opacity is added on top for the
   "translucent" mobile look (a plain SVG-child `filter:blur()` glow turned out unreliable

/* Static overlapping row: every card stays in its own left-to-right slot always (no reordering).
   Click a card (or its dot) and it grows to full size/full colour and comes to the front right
   where it sits; the rest stay put, smaller and grayscale. Pure CSS (:has() targets the card's
   own radio directly — no nth-child cross-referencing needed since nothing moves).
   Overlap is a fixed negative margin-left in a real flex row (not translateX sized off each
   card's own width), so every card still shows regardless of the mix of wide/narrow images.
   Each of the 3 non-active cards rests at its OWN fixed shrink (--cf-shrink set per nth-child
   below) rather than one shared amount, so the resting row has organic, slightly uneven heights
   instead of 3 identical ones. The container's height is a per-case, per-active-card
   calc()/clamp() (set via [aria-label]:has() below) tuned so the 4 cards, overlapped, always
   span the full content width (left edge to the hamburger icon's right edge) NO MATTER WHICH
   card is active — since growing a different card changes the row's total width, a single
   fixed height (matching only the card-1-active state) let the row overshoot past the edge
   once another card was clicked; this is why there are 4 height rules per case (one per
   possible active index) instead of 1. Coefficients are derived algebraically from each case's
   4 image ratios and the fixed per-position shrink amounts (see PLAN_ABC storyboard §5-2 for the
   formula). Each image keeps its own true aspect ratio (--r) at both sizes — nothing is ever
   cropped, stretched or letterboxed. No border on the card — the phone cutouts' rounded silhouette
   doesn't line up with a rectangular border, which left a stray straight edge visible in the
   corner; the drop shadow alone is enough definition against the dark page. */
