A live theme builder: one seed → the five runtime builders (color · type ·
depth · shape · space) composed in a single uix.eidos.applyTheme() call,
scoped to [data-tema-preview] so the themed mini-app re-skins while the
controls stay put. Five presets set all axes at once (a whole personality);
per-axis sliders + swatches for fine control; live code mirrors the actual
call. Self-contained (boots its own minimal ActiveUix + ActiveEidos with
applyDom). Preview is hand-built from foundation tokens (--color-{role}-* ·
--space-* · --radius-* · --font-size-* + data-shape/data-depth) — the exact
surface applyTheme drives — since component recipes are code-split.
Verified in browser: all 5 axes retune live (color hue follows the seed,
type ratio, shape smoothing/corner-shape, depth elevation, space density),
presets apply atomically, stable (no cycling), prerenders under
adapter-static.
