/* ============================================================
   Physical coordination — interactive image overlay styling.

   The photo + connector lines render inside one <svg> (.pc-svg)
   so there is a single paint layer. No CSS/SVG filters are used
   anywhere — a separate filtered layer over a plain <img> was
   blanking the photo on hover in Chrome. Beam glow = two stacked
   strokes (soft halo + bright core). HTML hit targets, captions
   and the hub badge overlay on top via z-index.
