/*
 * Sorbet — sherbet pop, playful-first. A toybox for adults with the
 * discipline of a real product theme: chunky corners, springy motion, and a
 * full sherbet palette (peach-coral, butter, mint, sky, berry) spent with
 * intent, not confetti. The paper stays a clean cool near-white — the warmth
 * lives entirely in the accents — and the ink is a soft berry-charcoal that
 * never goes harsh black.
 *
 * Palette rationale: every sherbet hue owns a semantic role. Peach-coral is
 * the hero and only the hero (--primary, chat-user, ring). Butter = warning,
 * mint = success, sky = info, raspberry = destructive. Fills are bright and
 * carry dark berry ink on top (the ivrea pattern) because pastel + white
 * text always fails the contrast floor. Muted surfaces get a barely-there
 * peach tint (chroma ≤ 0.015) so the neutrals lean toward the brand without
 * turning cream. Dark mode is "sorbet at midnight": deep plum-charcoal with
 * a berry undertone — never blue-gray — with the sherbets luminous on top.
 *
 * Token contract matches lib-theme-pristine/theme.css.
 */

/*
 * Fonts: consuming apps should load Bricolage Grotesque + Figtree +
 * JetBrains Mono at the top of their entry CSS (where @import statements
 * are allowed), via the Google Fonts URL documented in this theme's README.
 * Embedding the @import inside this file — or smuggling the URL in a
 * comment for a build script to lift — breaks PostCSS's ordering rules when
 * the theme is imported after other statements, so neither is done here.
