feat(demos): /temas/profundidad showcase — the two moments of depth, live

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).

/**
* Depth demo — the Eidos depth system, the novel "depth occurs" channel.
*
* Two moments, both live:
* - ESTADO: the 5 planes (`data-depth`) — the resting elevation (where an element *is*),
* composing surface + shadow + z. Toggle light/dark to see the mode-aware mix.
* - EVENTO: stamping `data-event-*` (as sema would during the hold) fires the firma —
* emerge → the shadow GROWS (rise); contact → it FLATTENS (recede). Depth *occurs*.
*
* Self-contained: imports the eidos foundation (planes + firma keyframes) + `data-theme`.

<strong>Default fuerte, jaula abierta.</strong> El set de planos, su mezcla y la firma son
config-driven y anulables; los primitivos (<code>--shadow-*</code>, <code>z-index</code>,
<code>box-shadow</code> crudo) siguen a un paso. La capa eventful es <em>aditiva</em> sobre el
plano de reposo — un elemento <i>flush</i> no eleva nada; uno <i>raised</i> sube proporcional
a su plano. Y degrada con <code>prefers-reduced-motion</code>.
