Two reported symptoms that turned out to be one bug, plus the dark
mode the user described as "too black".
The `hidden` attribute does nothing on the discount controls
`hidden` is implemented by the UA stylesheet as `[hidden]{display:none}`.
Any author rule that sets `display` outranks it — and `.totals` and
`.discount-body` both set `display:flex`. So `el.hidden = true` was a
no-op on both:
- the discount tier panel could not be collapsed, making "Add
discount" look like a dead control;
- the Discount totals row stayed on screen after the discount was
cleared, still showing the last figure (R 98.37) under a total
that no longer contained it. The JS only ever set `hidden` and
never cleared the text, so the operator had no way to tell stale
text from a live one.
`.cat-menu` and `.cat-backdrop` already carried per-element
`[hidden]{display:none}` overrides for exactly this reason; the two
discount elements were missed. Replaced with one global rule so the
whole class is covered rather than relying on each element to
remember. The clear path now also blanks the amount.
Verified statically rather than in a browser: jsdom does not model
the UA-vs-author cascade and reported the broken and fixed cases
identically, so the cascade was checked by resolving which rules
apply. Regression test fails without the fix.
Dark palette
The POS canvas was #0f0f0f (L* 4.3 — effectively black) with
surfaces only 3-4 L* above it, mixing a warm #1c1416 against a
neutral #181818 in the same UI. That near-black base plus two
competing surface tones is what read as muddy. Replaced with a
single cool-neutral ramp with four real steps, and menus/modals now
sit on a `--raised` layer instead of reusing the surface colour.
`#717171` was the secondary text colour in 25 places and measured
3.93:1 on the old canvas — below WCAG AA. It now measures 6.49:1.
Both the text greys and the surfaces were hardcoded per component
across seven POS pages; they are now tokens, with the dark block
rebinding them.
The shared `.dark` block in themes.css (drives all 24 themes) sat at
oklch(0.15) ≈ L* 3.1. Lifted +0.04 across the ramp, preserving its
shape and separation; muted-foreground goes 6.32:1 → 5.95:1, still
above AA. Cursor/Supabase, which override it darker, were at L* 1.3
and lifted too.
Service worker cache bumped to pos-v36 — pos.html and pos-app.js are
served cache-first, so without the bump the tills keep serving the
broken files.
3863 tests pass (3 new); build clean.
