/* Wiki styles. Colors and fonts come only from the brand tokens at the top of :root:
   --bg, --panel, --line, --ink, --muted, --accent, --link, --button, --on-button, --font-body, --font-head.
   --accent is for fills and decoration; text that needs contrast uses --ink, --muted or --link.
   Primary buttons are --button with --on-button text.
   Layout: 220px sections | page | 220px "On this page" from 1200px. Below 1200px the contents list
   sits above the body, and below 900px the sidebar folds into the "Menu" toggle. No JavaScript. */

/* The look: warm cream surfaces, near-black ink and one bright orange, set in Poppins. No company name or logo: the
   mark in public/brand/ is a plain icon. The orange is too light for small text (under 3:1 on cream), so it only fills
   buttons and draws accents; text that needs to read as a link uses the darker --link. Contrast ratios (WCAG):
   - --link (#b33800) on --bg 5.5:1, on --panel 4.9:1;
   - --on-button (#262423) on --button 4.7:1, and higher on the lighter hover fill (82% --button, 18% --bg);
   - --ink on --bg 14:1, on --panel 12.7:1; --muted on --bg 6.5:1, on --panel 5.9:1. */

/* Poppins 400/500/600 (SIL Open Font License, public/brand/fonts/OFL-poppins.txt), in two subsets from
   @fontsource/poppins. Latin-ext covers Polish and French letters (ł, ś, ż, œ). Where ranges overlap the later rule
   wins, so each weight lists latin-ext first, as fontsource does. */
