/* Hallmark · tokens · theme: Terminal
 * axes — paper band: dark (L 15.5%) · display style: mono · accent hue: amber phosphor (74°)
 * Anchor hue 74. Every neutral carries a trace of it, so the greys read warm rather than
 * clinical. Derived from the TUI palette in src/theme.ts — the lightness ramp is preserved
 * (18% / 32% / 62% / 94%); the hue is rotated from zinc-cool to phosphor-warm so the
 * neutrals agree with the accent instead of fighting it.
