/* site.css — the psychology pages (foshchii.com/psychology/).
   Same bones as the main site: Space Grotesk headings, Instrument Sans body,
   IBM Plex Mono labels, hairline rules, square corners. Calmer palette:
   a sage accent with neutrals tinted toward it, light by default and dark
   when the visitor's system asks for it.
   Plain HTML and CSS, no JavaScript, and the fonts are self-hosted, so a
   visit makes no request to anyone but this site. */
