`--depth-{plane}-scrim` was declared (DepthPlane field, DEPTH_CUES, validation,
applyDepth) but never seeded, emitted or read — a write-surface with no reader
(applyDepth({p:{scrim}}) silently no-op'd; never present in generated base.css).
Analyzed via workflow (state map + 4 dispositions + adversarial stress). The
four collapse to prune vs promote-to-z-parity: wire-and-unify SINKS (contradicts
the test-locked z open-cage precedent + the MD3/Radix/Vaul consensus that the
veil is component-owned, not an elevation cue), relocate flips its verb to
retain, and complete-to-z-parity would mint a third alias of the --color-overlay
backdrop role. Unlike z (kept as an exposed open cage — it varies per plane and
is unpaintable-forever), scrim has no per-plane variance and no value to seed.
Prune: remove scrim from DepthPlane / DEPTH_CUES / validation / emitter +
applyDepth doc. Amend rfc-depth.md (token contract + Phase-4 note + atmosphere
rows), reference.md cue list, changelog, pendiente. The modal veil stays where
MD3/Radix/Vaul + the standing decision put it: --{component}-overlay-* tinted by
--color-overlay.
Zero observable change (never emitted). Tests 71/71; npm run check src/ = 9
baseline, 0 new; base.css unchanged.

DEPTH_ENGINE_RFC (149 L) -> rfcs/rfc-depth.md and SHAPE_ENGINE_RFC (162 L)
-> rfcs/rfc-shape.md, Spanish to English. Both stubs summarize the shipped
state (phases 1-5) and keep the by-path citations resolving — including
the '// (DEPTH_ENGINE_RFC s5)' comments across src/uix/eidos/lib/*.ts that
decisions.md documents as load-bearing. decisions.md index rows repointed
and their Status column aligned with the status the RFCs themselves
declare (both said implemented; the rows still said Propuesta). Theming
reference s29/s30 canonical-guide links swept. docs:check 0 errors.
