Depth engine — Fase 2 (mode-adaptive mezcla):
- New `halo` cue per plane: a top-edge rim-light computed in oklab
(color-mix(in oklab, white N%, transparent); 5/7/8% on raised/overlay/modal).
The `[data-depth]` box-shadow now composes `shadow, halo`. Invisible on light
surfaces (the drop shadow leads), the lift cue on dark surfaces (where the drop
shadow barely shows) — the mode-adaptive answer to "shadow lies in dark",
scoped to the depth channel (global --shadow-* untouched).
- Wired through config-types (DepthPlane.halo) + render-css (declare + compose)
+ config validation + STATIC_DEPTH + regenerated generated/base.css.
Showcase — /temas/profundidad to reference depth (4 -> 9 sections): matches
Material elevation catalog breadth and adds the two axes it lacks (eventful +
open cage):
- Responde a cada estado — dynamic elevation, live interactive control
- La escalera de planos — z-stack of the 5 planes
- Catalogo de planos en reposo — the resting-elevation spec table, our vocabulary
- Luz vs sombra — light/dark side-by-side showing the halo mechanism
- Accesibilidad — never the only channel, reduced-motion, forced-colors, contrast
- Fix: mirror data-theme onto <html> so :root depth tokens stay mode-aware
Docs: DEPTH_ENGINE_RFC (Fase 2 + 5 done, token contract + halo), THEMING 29.
Verified: npm run check 0 errors; depth tests 50/50 (updated the box-shadow
assertion to the shadow,halo composition). Pre-existing `words` recipe-contract
failures unrelated.

The first cut was weak (grey tiles + a "dispárame" box — it did not sell depth).
Rebuilt around real UI that responds:
- Reacciona — metric cards that lift on hover (raised -> overlay: shadow grows +
translateY): depth responds to interaction (state moment).
- Asciende — an app mockup whose trigger rises a dialog over a scrim; the dialog
shadow grows from flat -> its modal plane as it ascends (the present-rise firma,
fired by stamping data-event-*) and the backdrop recedes (event moment).
- Cada plano, un rol — the 5 planes as the real components they are for:
chips (flush) / card (raised) / menu (overlay) / dialog (modal) / input (recessed).
Self-contained, dark editorial aesthetic. Verified: check 0 errors; browser — the
dialog rises with the firma over a scrim (firmaFired + scrim true), archetypes render
with their plane shadows.

Showcase for the depth channel (mirrors /temas/color and /temas/tipografia):
- ESTADO: the 5 planes (flush/raised/overlay/modal/recessed) as elevated tiles
composing surface + shadow + z (`data-depth`), with a light/dark toggle showing
the mode-aware mix.
- EVENTO: stamping `data-event-*` (as sema would during the hold) fires the firma
live — emerge -> the shadow grows (rise); contact -> it flattens (recede).
Depth occurs.
Self-contained (eidos foundation + data-theme), distinctive dark/editorial aesthetic.
Verified: check 0 errors; browser — 5 planes render with their resting shadows;
firing emerge applies the present-rise firma (firmaFired true).
