CODE-REVIEW-649-r1 M1: the 2.5D beam's cut by physical bodies (AC7) had no
witness. Unit: a column in the beam leaves the floor between window and
column lit and shades it behind the column; smoke: a Solid partition across
the south beam removes floor from the rendered wash. Mutants: occluders
extruded toward the sun, occluders ignored, card drops occluders.
Lows: L1 stale alpha wording (DEVELOPMENT, ARCHITECTURE, card comment,
benchmark); L3 dark-theme state edges computed per theme; L4 Alert beats a
plain Hover and a plain Selected; L5 a virtual marker has no dashed ring;
L6 tiles and shadows stay without walls (show_borders off).
Issue: #649
User-Visible: no
- settings.volumetric_view (General settings › Display, third switch) replaces
the alpha entry, the header projection toggle and the phone-menu item; one
rule for card, sidebar page and kiosk; editors stay Flat; backend accepts
only a boolean, support package copies it.
- Raised tiles in 2.5D View: no ring, rounded body min(0.275 D, 0.3 h), edge
0.1 D with the lab filters, ×1.12 size also in layout/collision, lift
0.075 D, one floor-shadow layer under all markers (theme × floor table),
frames hugging tile and edge (Alert > Focus > Selected > Hover), forced
colours without edge and shadow (src/iso-tiles.ts, styles/iso-tiles).
- Soft sun wash instead of projected Flat wedges (src/iso-sun.ts): same gates
and windows as sun_rays, length from elevation, parallelogram along the sun,
tone and streaks by floor lightness, sill line.
- Walls take the user's wall colour (top opaque, sides × .77/.68/.60); theme
rules for walls/openings/labels removed; furniture uses the Flat stroke rule.
- Smokes smoke_iso_tiles/iso_sun/iso_theme_walls/volumetric_setting, 16 new
mutants, acceptance scenes STAGE6_ACCEPTANCE_SCENARIOS (golden with their
Linux CI baselines), ACCEPTANCE.md side by side.
