/* demiros.ai — the stylesheet every page shares.
 *
 * Plain CSS, no framework, no build step, no tracking. Built from the
 * website's approved prototype (seven pages, a shared Nav and Footer). The
 * colours and type are the brand's own tokens (/brand/tokens.css) and the
 * mark's states are the brand's one motion stylesheet (/brand/motion.css).
 *
 * Amber means only "waiting for your yes": the breathing ring, the waiting
 * card's edge and its one action. Every main button is cream on ink.
 *
 * Motion only where a state changes: the waiting ring breathes, the mark
 * moves while a run is thinking, working or checking, and sections fade in
 * once as they arrive. Every one of them stops under reduced motion.
 *
 * One header and one footer on every page; their markup comes from
 * scripts/site/build_use_cases.py, which writes every page, and
 * scripts/site/check_shell.py fails while any page's copy differs.
