/* docs.css — styling for the DumpDraft documentation pages.
   Brand-consistent with the app (same colors, fonts, teal accent, dark mode),
   but a normal scrolling document layout instead of the app shell.
   Designed to be calm and readable: generous spacing, strong contrast,
   large tap targets, reduced-motion friendly — the same accessibility ethos
   the app itself is built around. */
