/*
 * Harbor — cool neutral, warm spark.
 *
 * The most neutral of the warm-consumer set. The whole surface is a calm,
 * faintly-COOL light grey — morning harbor light on soft slate, a whisper of
 * blue-grey that reads as clean neutral, never cream, never SaaS blue. All the
 * warmth in the theme is delivered by ONE honey/amber accent (hue ~78), spent
 * surgically on the primary action, selection, and focus ring — grey stone
 * warmed by lamplight. Ink is a deep, very-slightly-cool charcoal; the amber
 * carries dark ink on top (the bright-swatch/dark-ink pairing) so it lands high
 * above the contrast floor while staying quiet everywhere else.
 *
 * Dark mode is the harbor at night: a deep cool-neutral charcoal (low chroma,
 * faint cool hue ~250, not pure black and never warm-brown) with the same amber
 * glowing warm against it. Crisp, quiet, trustworthy — a calm utility that is
 * warm only at the touchpoints. Built for me.sky-ai.com back-of-house.
 *
 * Type is crisp modern-neutral: Inter Tight for text, Geist for headings, Geist
 * Mono for code. Product register — fixed rem sizes, no serif. Radius is a
 * crisp 0.75rem; shadows are low and neutral; motion is product-fast.
 *
 * Token contract matches lib-theme-caffe-florian/theme.css (Crema v1).
 */

/*
 * Fonts: consuming apps load Inter Tight + Geist + Geist 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 here — or
 * smuggling the URL in a comment for a build script to lift — breaks PostCSS's
 * ordering rules, so neither is done in this file.
