/* HealthSync UI — the single stylesheet for every page.
 *
 * Design rules, so the pages stay consistent as they grow:
 *
 *   1. One accent colour (teal) carries interaction and "this is a link/action". Everything
 *      else is neutral. Metric families get their own tone through --tone, so a heart rate
 *      and a step count never look like the same number in different clothes.
 *   2. Cards are a single layer. A card inside a card means the layout has not decided what
 *      the grouping is; sections inside a card are separated by a rule and a heading instead.
 *   3. Space is the structure. Sections get 24px, cards 16-20px, rows 8-12px — the page keeps
 *      its rhythm without borders on everything.
 *   4. Mobile first: the layout is built at 360px and widens. Most readers are on the phone
 *      the watch talks to.
