   Light is the base. Dark redefines only the tokens, never the rules, so a

   over the network: no web fonts, no CDN, no external stylesheet. That keeps
   the page fast, keeps it working inside a strict content policy, and means a
   visitor on a charity's locked-down desktop gets exactly what we designed.

   Round 14: drawn diagrams and pull quotes.

   The diagrams are inline SVG written by lib/diagrams.mjs. Not one colour is
   set in the markup: every fill and stroke is a class here reading the same
   tokens as the rest of the page, so a diagram follows the light and the
   dark theme without a second drawing, and no inline style attribute is
   needed, which matters because the content policy sets style-src to 'self'
   with no unsafe-inline.

   Sizing. Each diagram is drawn in a 400 unit viewBox and capped at 30rem.
   At a 390px viewport the wrap leaves 350px, so it renders at about 0.88 and
   a 15px label lands near 13px. On a wide screen it renders at about 1.2 and
   the same label lands near 18px. Both are legible, which is the point.

/* Bottom margin as well as top: the element after a figure or a pull quote
   is usually a paragraph, and a paragraph only gets a top margin when it
   follows another paragraph, so without this the copy butts against the
   drawing. Adjacent block margins collapse, so a list after a figure still
   gets one gap and not two. */
