 * Design tokens (colours, type, spacing, radii) live in tokens.css, imported below.
 * Page <style> blocks should only use var(--…) values from there, never raw colours,

 * Plain CSS, no build step, no external fonts or CDN requests.
 * Mobile first: base rules target ~375px phones; min-width queries add layout.
