/* cloudairy-brand.css — the shared Cloudairy design tokens.
 *
 * One source of truth for pages that are authored outside the legacy
 * assets/main.css sheet (currently /ai-project-management and /lp/projects), so
 * they read as the same product as the rest of cloudairy.com instead of as
 * one-off landing pages.
 *
 * Palette verified 2026-08-27 by frequency analysis of this repo and
 * cloudairy-board-frontend/src — the marketing site and the app use the same
 * values, so these are the real system rather than a marketing-only skin.
 *
 * Typeface is DM Sans, the site- and app-wide face. The @font-face rules live
 * in assets/main.css / assets/lp/site-main.css; this file only references the
 * family, so load one of those (or the Google Fonts link) alongside it.
