     /life-at-ria/            album grid + category filter
     /life-at-ria/<slug>/     one page per album, gallery + lightbox

   The HERO is not styled here: it reuses the approved product hero
   (.pd-hero / .pd-hero__grid / .pd-hero__shot) from product-detail.css,
   which both pages load. Same stylesheet, so it cannot drift.

   Namespace: lf-  .

   CLIENT RULES: linear gradients only, no circles, no "01/02" numbering,
   motion never wrapped in a reduced-motion query.
   HOUSE RULES: clamp()/calc() need SPACES around +/- ; grid/flex children
   that hold text need min-width: 0 .
   ========================================================================== */

/* Tighter than the shared .section (up to 6.5rem top AND bottom).
   MUST be `.r3 .x`: the shared rule is `.r3 .section` (0,2,0), so a bare
   class (0,1,0) loses and the tightening never applied. */

   ALBUM GRID
   Every tile is identical: a fixed 4:3 cover plus a body. Albums whose
   description the client never wrote simply have a shorter body — the cover
   is what sets the row height, so the grid stays level either way.
