Includes the 2026-07-07 UX sweep: neutral inline-code chips (accent reserved for actions/links/focus), dark-mode card/popover lightness lift for visible surface separation, 44px touch-target floor on coarse pointers, card-title pinned to a named ramp role.

Siena — drenched Mediterranean courtyard. Warmth carried by the surface itself: the background is a real terracotta wall (not a tinted near-white), cards are sun-bleached plaster panels resting on it, and the ink is deep warm olive-brown. Primary is burnt sienna; one cool Mediterranean blue is spent on accent and info so the heat has a counterpoint. Dark mode is the same courtyard at dusk — umber-brown surfaces, terracotta turned to glow. Fraunces display voice over Albert Sans, modest 0.75rem corners, low warm shadows: things rest on the wall, they don't float.
Fonts
Consuming apps must load the theme's fonts at the very top of their entry CSS
(app/app.css), before any other statement:
@import url("https://fonts.googleapis.com/css2?family=Fraunces:opsz,wght@9..144,500;9..144,600;9..144,700&family=Albert+Sans:ital,wght@0,400;0,500;0,600;0,700;1,400&family=JetBrains+Mono:wght@400;500&display=swap");
- Fraunces (500/600/700, variable optical size) —
--font-heading/--heading-family - Albert Sans (400/500/600/700 + 400 italic) —
--font-sans/--body-family - JetBrains Mono (400/500) —
--font-mono
Do not @import fonts inside theme.css — per the token contract, fonts load
from the consuming app's entry CSS only.
Usage
Clone as a sibling lib and point the app's theme import at it:
/* app/app.css */
@import "../../lib-theme-siena/theme.css";
Contract
Passes the Crema token contract v1:
node create-crema-app/scripts/validate-theme.mjs lib-theme-siena/theme.css
All Tier-1 tokens defined in both :root and .dark; contrast floors verified
(foreground/background 10.0:1 light / 14.1:1 dark; every paired -foreground
≥ 5.3:1). Glass tokens are inert stubs; springs alias to standard easings
(calm-theme pattern); no font-size on root.
