Extracted from asger.weirsoe.dk (src/styles/global.css). Tokens (--color-*) +
base layer (glow, selection, smooth theme transition) + .wt-* components +
.prose, plus a persisted dark/light toggle (weirsoe-theme.js) and a Bulma
adapter (adapters/bulma.css) so existing Bulma sites get the card look without
markup changes. Pure CSS, system fonts, no external requests.
