/*
 * Solarium — botanical sunroom theme. Morning light through glass, humid air,
 * leaf shadows, citrus on the table. FRESH-warm, not baked-warm: the warmth
 * comes from light and living things, not from brown or orange pigment. Body
 * surfaces are a pale neutral tinted toward the theme's own green-amber hue
 * (~120) — light through leaves, never parchment. Ink is a deep green-charcoal;
 * the primary is a confident deepened fern that carries warm-white labels; the
 * single warm pop is an apricot accent that keeps the palette consumer-warm
 * rather than clinical-green. Success shifts toward emerald so status green
 * never collides with the brand fern. Dark mode is the sunroom at night: deep
 * green-charcoal (never blue-gray), plants as silhouettes, an apricot lamp
 * glow, and a primary that brightens to a luminous fern with dark-ink labels.
 *
 * Token contract matches lib-theme-pristine/theme.css.
 */

/*
 * Fonts: consuming apps should load Gantari + 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.
