Follow-up to #2570, which merged before this review fix was pushed.

What changes

#2570 gave selected text the primary's 40% wash and forced it to foreground. A review pointed out that this still fails on a filled surface: selecting the label of a primary badge, a selected choice card or a calendar day puts light text on an orange fill at about 2.1:1 in the dark theme.

• Selection is an opaque pair, primary-foreground on primary. Neither half depends on what is underneath, so selected text reads the same over plain text, a muted run or a tone.
• A chip keeps its own look when selected. A band inside a filled chip only fights the fill: an orange block in the middle of a red FATAL badge. A kit badge, and a label on a solid fill (text-on-fill, text-primary-foreground), now keep their fill and ink, and a thin underline in that ink marks the selected letters, so a partial selection is still visible.
• native-select.styles.ts drops its own selection: utilities. They set the same pair, and docs/design-rules.md says no call site carries one.
• docs/design-rules.md states both rules.

Verified

• bunx oxfmt --check, bunx oxlint -c .oxlintrc.effect.json --quiet on the changed files, bun run check:tokens, bun run lint:ui-baseline (687 to 687): clean.
• The chip rule read from computed styles on the FATAL chip, selected: background rgba(0, 0, 0, 0) and colour oklch(1 0 0) (its own ink) in Chromium and in WebKit, both themes, and the underline is drawn in both (screenshots below are Chromium). Firefox was not run: no matching browser build on this machine.
• The opaque pair read from computed styles on the preview at e5c8904, both themes (comment below).

Preview check

Read on app-pr-2573.maple.dev/logs in a real browser (Playwright, signed in as the preview reviewer), getComputedStyle(element, "::selection"):

Theme	Element	Background	Colour
Dark	body text	oklch(0.74 0.15 62)	oklch(0.18 0.01 62)
Dark	muted text	oklch(0.74 0.15 62)	oklch(0.18 0.01 62)
Light	body text	oklch(0.7 0.155 60)	oklch(0.2 0.01 60)
Light	muted text	oklch(0.7 0.155 60)	oklch(0.2 0.01 60)

Those are --primary and --primary-foreground in each theme, the same pair on normal and muted text.

No server code changes here, so there are no new traces to look at.

Maple review

🟢 Confidence 10/10 · safe to merge. Opaque pair computes to 6.5:1 (light) and 7.9:1 (dark), and the chip rule reaches the kit path that renders every badge.
_{no findings · tests not needed · risk medium}

Makes ::selection an opaque primary-foreground on primary pair and exempts chips (badges, text-on-fill, text-primary-foreground) from the band, plus matching design-rules text. Contained CSS change, safe to merge.

• ::selection pairs primary-foreground on primary instead of a 40% wash
• Chips drop the band for a 1px currentColor underline
• native-select.styles.ts loses its own redundant selection: pair
