/*
  Light theme by default; the dark theme (warm black + orange) is applied via
  [data-theme="dark"] on <html>, set before first paint by the inline script in base.html.

  Spacing: one scale (--space-*). Between the blocks of a page, spacing comes only from the
  `gap` of `.page` / `.stack` containers, never from margins on the blocks themselves; this
  keeps every page on the same rhythm when blocks are added or removed.
