/**
 * Design tokens — the Cobalt palette.
 *
 * The blue everything infrastructure is, done properly rather than by default — high chroma at 212°, with a lighter azure accent to keep it off the navy end.
 *
 * This file is the reason a pasted block looks right. Every block and page
 * styles itself with semantic classes — `bg-card`, `text-muted-foreground`,
 * `border-border` — rather than literal colours, so they inherit whatever
 * you define here instead of fighting it. Change a value below and every
 * section in the project moves with it. Change the hue on `--primary` and
 * `--ring` together and you have rebranded the site.
 *
 * Values are bare HSL channels, not `hsl(...)` calls. That is what lets
 * Tailwind compose them with an alpha suffix: `bg-primary/10` expands to
 * `hsl(var(--primary) / 0.1)`, which is impossible if the variable already
 * carries its own function wrapper.
 *
 * Every foreground/background pair below clears WCAG AA (4.5:1) in both
 * themes. If you retune one, check the pair rather than trusting the eye —
 * mid-lightness accents are the ones that fail.
