ui-maps

UI → every material map. Thirty scenes, one map (or one combo) each, always the SAME dashboard so the maps compare like for like.

Read the rig's notes

The twin of html-maps.promo. `source(factory="ui/scene" …)` is accepted under
ANY `<slot>_from`, so one ui stage can be the colour map, the emissive, the
roughness, the bump, the parallax height, the cut-out, the lacquer mask, the
sheen tint… of one material. Devices take the same blocks as children of the
tag (`laptop > roughness_map_from > source`) plus `screen-<prop>` scalars.

Where html and ui part company: an `html` under a slot can be RE-RASTERED as
data (`relief=luma|alpha|ao|depth|normal`), so the one colourful page drives
every slot. A ui stage has no such derivation — so each data map here is
AUTHORED as its own stage, drawn from the same layout: a grayscale twin for
height, a black/white block mask for "cards vs page", an accents-only stage
for emissive, a layered-gray stage for depth, and a real tangent-space
normal map (flat #8080ff, bevelled edges) for scene 03. That is the ui
idiom: the data map is a design, not a derivation.

Scenes 21–22 substitute an explicit `light(type=area)` for html's `emit=<n>`
(a ui stage is not a RectAreaLight source) — the light is sized and coloured
to the panel it stands in for, which is what `emit` computes.
