/* Coaching Portal: stylesheet of the redesign (2026-09).
 *
 * Pages built on base_app.html use this file. Pages that are not redesigned
 * yet still use style.css; that file goes away when the last page has moved.
 *
 * Rules behind every choice below (decided with Marc, 2026-09-21):
 * - Dark is the default theme. Light is opt-in via <html data-theme="light">.
 * - Three signal colours, everything else is grey. Blue = action, done, coach
 *   feedback. Gold = reward. Bright red = danger. Green and red are never
 *   used as opposites: colourblind people see them alike.
 * - Colour never carries a meaning alone: each state also has a shape, an
 *   icon or a word.
 * - A phone is narrow. No box inside the screen, no double padding. A screen
 *   is a stack of bands from edge to edge, separated by hairlines and by two
 *   ground tones.
 * - Everything tapped in the gym is at least 48px high.
 * - Numbers use the monospaced font, so they line up in columns.
