/* --active-color is set on .process-visual by initProcessVisual() in main.js and
   inherited by both the photo panel and the dots below it. Not position:sticky —
   the interaction is hover/tap-driven, not scroll-driven, so the panel stays level
   (top-aligned via .process-layout's align-items:stretch) with the heading+list
   column instead of detaching and drifting out of alignment as the page scrolls.
   On desktop/tablet the panel stretches to match .process-left's own height (heading
   + list combined), so it starts level with the heading and ends level with the last
   step — no fixed aspect-ratio, no leftover empty space. On mobile, where the photo
   sits below the list instead of beside it, it falls back to aspect-ratio:3/4 (see
   the max-width:719px breakpoint below) since there's no column height to match.
   max-height is a safety cap: if the column ever renders taller than a sane photo
   proportion (longer text wrap, different font metrics, a bug), the panel stops
   growing there instead of turning into an oversized box. */
