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

     --paper and 2.96 on --panel — the last being the "Off" status pill, the
     only state indicator on a group-landing card and the smallest type on
     screen. Fixing the token rather than the call sites covers all 102
     usages at once — including Pro's panels, which render inside
     #xspeed-app and ship no tokens of their own.

     The first pass at this (#6B7180) only measured the three neutral
     surfaces and missed a fourth class: the TINTS. text-muted is never
     paired with a *-tint class on the same element — the tint sits on an
     ancestor upsell card — so a source grep finds nothing and only a
     rendered-DOM measurement catches it. #6B7180 failed on all four
     (4.35 / 4.43 / 4.49 / 4.28).

     #686D7C is the lightest value on the same hue that clears 4.5:1 on
     every surface a muted string can land on:

       canvas 4.99 · paper 5.16 · panel 4.77
       primary+info-tint 4.60 · success-tint 4.68

/* ---- MCP discovery card (Overview, disconnected) ----------------------- */
/*
 * Three tinted surfaces for the "Control and optimize your site with AI" card.
 * They live here rather than in a component because Tailwind cannot express an
 * ALPHA of a var()-backed colour: with `primary: 'var(--primary)'` in the theme,
 * `border-primary/45` silently emits the colour at full strength. Deriving them
 * from --primary with color-mix() keeps the card on-brand in both themes with
 * no new tokens — change --primary and all three follow.
 *
 * Every rule declares a neutral fallback FIRST. color-mix() is ~2023-era, and
 * where it is unsupported the declaration is dropped: without the fallback the
 * card's border-color would fall back to currentColor, painting a near-black
 * hairline around a white card. The fallback degrades to the plain --line
 * border and no wash, which is simply the standard card treatment.
