/* ehsto.dev — app chrome
 *
 * Styles for ehsto.dev's own UI:
 *   · Style Guide (component entry, colour grid, settings controls)
 *   · Doc sections (Style Guide + Core long-form pages)
 *   · Brief intake (editor, preview, progress, actions)
 *
 * These rules are NOT part of the portable design system. Consuming
 * projects load style.css alone; ehsto.dev loads style.css + this file.
 *
 * Load order in index.html matters: style.css FIRST, app.css SECOND.
 * Rules here can extend or override framework primitives via the
 * cascade — but only because they come later.
