   Layout: a single-column stack of cards on small screens, widening to a
   two-column document/results split at 1080px.

   Theming: every colour is a token on :root. Light is the default (documents
   are read on white); dark is applied for prefers-color-scheme and for an
   explicit [data-theme] override from the toggle, so the toggle wins in both
   directions.
