/* Hallmark | custom theme "Pole" | genre: atmospheric-light | tone: confident, precise, quiet
 * paper oklch(98.6% 0.002 260) / oklch(15% 0.012 265) | accent oklch(62% 0.19 255) blue
 * display + body: Inter (self-hosted, variable) | mark: gradient squircle from the PlanPole logo
 * axes: paper-band light+dark / grotesk-sans / cool

 * Source of the palette: the PlanPole mark (accent #0a84ff to #5e5ce6) and the app's own
 * design tokens (src/styles/tokens.css: bg #fafafa / #0b0d12, muted #6e6e73). Text-safe accent
 * variants are separate tokens because the pure brand blue is under 4.5:1 as small text on paper.
