/* ============================================================
   tokens.css — Cobalt terminal (dark) design tokens
   Single source of truth for colour, type, radius, shadow, motion.
   Blue-family terminal theme, deliberately not green-on-black.

   Contrast is computed, not eyeballed. On --bg #0e1116: ink 15.55, ink-soft 12.64, muted 6.38,
   faint 4.79, bayside-text 5.51, cmd 10.90, ok 10.86, warn 11.05. On --surface #161a21: ink 14.34,
   ink-soft 11.66, muted 5.89, bayside-text 5.08, cmd 10.05; --faint 4.42 is AA-large only, so
   captions, never body text.

   Two-step accent: brand Bayside Blue #277CE0 is 4.54:1 on the canvas and 4.19:1 on a panel
   (white on it 4.16:1), so it fails AA as small text — --cobalt-text is the same hue one step
   lighter (5.51 / 5.08) for links and prompts. Buttons use --ink-dark on --cobalt.

   --line / --line-strong (1.36 / 1.65) are decorative dividers, not UI boundaries, so 1.4.11
   does not apply; real boundaries (focus rings, active borders) use --cobalt.
