/* ============================================================
   GROWING UP AT HOME — Sampler / Cross-Stitch Grid
   Archetype signatures (this site only):
     1. stitch rule      — running-stitch dashes (11 on / 7 off)
     2. sampler band     — split solid indigo strip above the masthead
     3. misregistration  — hard-edged mustard offset shadow on solid plates
   Shape lock: radius 0 everywhere. Only exception: category chips (2px).
   Color lock: indigo = structure, mustard = only accent.
   Motion: CSS hover + CSS scroll progress. Zero JS.
