   Тёплый Контур: остекление балконов, Ярославль
   --------------------------------------------------------------------------
   Photography lives in img/. Containers (.visual-panel, .tile-photo) own
   the aspect-ratio and radius; images fill them with object-fit: cover,
   so replacement photos need no CSS changes.
   --------------------------------------------------------------------------
   Corner radius rule: buttons are 12px, selector pills are full-pill (999px),
   cards and panels are 18px, inputs are 10px. No other radii.
