/* LapseCoin UI, shared layer. Per-page rules live in css/pages/<page>.css.
 *
 * Visual language (checked against Linear, Vercel, Stripe, Blockscout and
 * mempool.space screenshots, not only their CSS):
 *  - Geist Sans for everything, Geist Mono only for hashes and addresses.
 *    Numbers are sans with tabular figures. Big figures are large and tight,
 *    labels are small and muted: the size contrast carries the hierarchy.
 *  - White surfaces on a warm tinted page, 10px radius, a 1px low-contrast
 *    border and a barely visible shadow. Light header with a hairline.
 *  - One accent for links, focus and the active state. Status colors are
 *    muted and appear on text or a small dot. No gradients, no glow, no glass,
 *    no emoji icons, no purple, no stripe-on-the-left-edge cards.
 *  - Every grey is the ink at an opacity (--ink-rgb), so the palette stays warm.
 *  - Use the page's width: put things side by side (.cols) so a page fits
 *    without scrolling when there is room, and stack below 900px.
