Includes the 2026-07-07 UX sweep: neutral inline-code chips (accent

+# lib-theme-sorbet
+
+Sherbet pop, playful-first. Sorbet is the toybox theme of the Crema family:
+clean cool near-white paper with berry-charcoal ink, a peach-coral hero spent
+surgically, and a full sherbet set where every hue owns a semantic role —
+butter = warning, mint = success, sky = info, raspberry = destructive. Corners
+are chunky (1.375rem radius, buttons verging on pill), shadows are crisp
+small-offset stamps tinted toward berry, and motion is the springy one of the
+family — genuine `linear()` spring curves with real overshoot, not aliases.
+Dark mode is "sorbet at midnight": deep plum-charcoal with a berry undertone,
+the sherbets luminous against it. Bright fills always carry dark berry ink
+(the ivrea pattern), so every pairing clears the 4.5:1 contract floor.
+
+## Fonts
+
+The consuming app must load the fonts at the very top of its entry CSS
+(`app/app.css`), per the Crema font convention — the theme itself never
+imports fonts:
+
+```css
+@import url("https://fonts.googleapis.com/css2?family=Bricolage+Grotesque:opsz,wght@12..96,400;12..96,600;12..96,700;12..96,800&family=Figtree:ital,wght@0,400;0,500;0,600;0,700;1,400&family=JetBrains+Mono:wght@400;500;600&display=swap");
+```
+
+- **Bricolage Grotesque** (600–800) — `--font-heading`: bold friendly
+  geometric; headings run 700–800, the chunk is part of the voice.
+- **Figtree** (400–700) — `--font-sans`: tuned legible sans for UI and body.
+- **JetBrains Mono** (400–600) — `--font-mono`.
+
+## Contract
+
+Passes `create-crema-app/scripts/validate-theme.mjs` (token contract v1):
+all Tier-1 tokens in `:root` and `.dark`, every foreground/background pair at
+or above the WCAG AA floors, no font `@import`, no root `font-size`, inert
+glass stubs (`0px / 100% / 1 / 1`).
+
+## Usage
+
+```css
+/* app/app.css — fonts first, then under CREMA:SOURCES */
+@import "../../lib-theme-sorbet/theme.css";
+```
+
+Chart tokens are the five sherbets straight from the tub — coral 38°,
+butter 98°, mint 160°, sky 230°, berry 330° — hues ≥60° apart with staggered
+adjacent lightness so series stay legible for color-blind readers.
