/* donovanadkisson.com. One stylesheet, no web fonts (no third-party requests;
   the CSP allows only 'self').
   Palette "dark and amber" chosen by the owner 2026-10-30 (replacing the first
   clay-on-paper draft). Dark is the default; visitors whose device asks for light
   get the matching light version below. Every text colour meets WCAG AA (4.5:1)
   on both background shades: the light amber is darker than the dark one for that
   reason (#f2a541 would be under 2:1 on white). */
