/*
 * Republic OS — Atlas design system.

 * Ported from rc_atlas (see DESIGN.md). Flat, navy-tinted operations console:
 * one burnt-orange accent, DM type family (Serif Display / Sans / Mono),
 * 0px corners, 1px hairlines, NO shadows. Depth is tone + hairline only.
 *
 * Served as-is by Propshaft. Class names are kept stable so existing views
 * inherit the new look; values and component rules are retargeted to Atlas.
