/* /projects (v3) — "The spaces we build". Page layout + its one motion signature (DESIGN-V3 §8.7, §6.5):
   3D-perspective masonry that flattens as it arrives · filter re-flow (own FLIP) · shared-element zoom into the viewer
   (View Transitions API, FLIP fallback). Everything else (header, crumbs, hero entrance, form, reveals) is base.css.
   The masonry is laid out by projects.php (and re-laid by projects.js): each tile gets its column (--x) and its offset as a
   sum of height factors (--ya, × column width) plus a count of caption rows (--yn); two plans, 3 columns ≥ 1024 px and
   2 columns below. Column width comes from the wall's own width (container units), so nothing is measured by script and
   nothing shifts at load. Static (html.a-noanim / no-js / a-late): the same wall, flat, no lag. */
