#69: audit-theme-design tags hue/CVD/ANSI-family noise on white,
vantablack, lumon, hackerman, matte-black, miasma as [identity] with a
legend — do not retune identity palettes into traffic lights.
#70: import-palettes keeps surface≠overlay when color0==color8, derives
light UI chips from base (ANSI-black trap), gentler light mantle; roles
are first-class. No bulk re-import of shipped theme JSON.
Verified: V0 (py_compile + synthetic import fixtures + audit report).
tools/audit-theme-design.py (report-only, maintainer-run): for every
themes/*.json it checks OKLCH lightness architecture (raised bg stack,
fg hierarchy), WCAG contrast beyond the guarded pairs, status-color
hue families, accent harmony, protanopia/deuteranopia
distinguishability (Machado matrices), and ANSI slot semantics the
greeter/tty now rely on. Ran it over all 21 palettes + a visual pass
over representative previews; findings curated identity-aware (lumon/
vantablack/white/hackerman exemptions are identity, not defects) into
the P1-P3 punch list now recorded in BACKLOG item 28: two palettes
with literally invisible subtext (summer-day, flexoki-light — the
item-25/27 trap at its source), two inverted bg stacks (miasma,
kanagawa), muted/warn floors, a systemic "status is never color-only"
rule, the light-theme ANSI convention decision, and bar grouping
rhythm notes.
Verified: V0 (py_compile; the tool is report-only, deliberately not a
checks.* gate until slice b adopts rules + exemptions).
