Rebuilt from abstract tiles to a real "now playing" card whose every corner is
driven by a control panel — switch family / smoothing / magnitude / concentric and
the whole card retunes live. The avatar stays a true circle (families do not deform
it, by design). Plus: de-cerca round-vs-squircle, the 4 families on one chip, the
press-morph buttons, and a "what only Eidos does" strip.
Fix: the cover no longer sets its own border-radius, so the [data-shape-nest]
concentric rule owns it — the cover inset is now truly concentric (16 - 8 = 8px).
Verified: check 0 errors; browser (Chrome 146) — the family switch retunes card +
cover + play + tag + input live, avatar stays circular, cover concentric.
