2 * xSpeed dashboard design tokens + self-hosted fonts (redesign v2).
3 *
4 * Lives in public/ (copied verbatim to assets/ by Vite on build — NOT bundled)
5 * so the @font-face url('./fonts/…') references resolve relative to
6 * assets/theme.css → assets/fonts/…, and so the CSS variables are available to
7 * BOTH the Tailwind utilities in admin.css and every React component. Scoped to
8 * #xspeed-app; dark overrides ride the existing `.dark` class that useTheme
9 * (and PHP's server-side pre-paint) toggles.
10 *
11 * Fonts are Latin-subset woff2 (Inter 400/500/600, Space Grotesk 500/600/700,
12 * JetBrains Mono 400/500) — admin-only, ~168 KB total, font-display: swap.

47 --paper and 2.96 on --panel — the last being the "Off" status pill, the
48 only state indicator on a group-landing card and the smallest type on
49 screen. Fixing the token rather than the call sites covers all 102
50 usages at once — including Pro's panels, which render inside
51 #xspeed-app and ship no tokens of their own.
52
53 The first pass at this (#6B7180) only measured the three neutral
54 surfaces and missed a fourth class: the TINTS. text-muted is never
55 paired with a *-tint class on the same element — the tint sits on an
56 ancestor upsell card — so a source grep finds nothing and only a
57 rendered-DOM measurement catches it. #6B7180 failed on all four
58 (4.35 / 4.43 / 4.49 / 4.28).

60 #686D7C is the lightest value on the same hue that clears 4.5:1 on

64 primary+info-tint 4.60 · success-tint 4.68
65 warning-tint 4.74 · danger-tint 4.52

67 Still visibly lighter than --text-secondary (5.91 on canvas), so the
68 hint/secondary distinction the palette relies on survives. */

157 * `border-primary/45` silently emits the colour at full strength. Deriving them
158 * from --primary with color-mix() keeps the card on-brand in both themes with
159 * no new tokens — change --primary and all three follow.
160 *
161 * Every rule declares a neutral fallback FIRST. color-mix() is ~2023-era, and
162 * where it is unsupported the declaration is dropped: without the fallback the
163 * card's border-color would fall back to currentColor, painting a near-black
164 * hairline around a white card. The fallback degrades to the plain --line
