/* HHC's websites: one stylesheet for every site. The brand (concept C, 7 Nov 2026): Harper Green, limewash, stone and
   brass; Source Serif 4 for headings, Inter for text; line drawings in brass on each site's deep colour. Each site
   sets --accent (App.razor): its name, buttons and details, and a deep version of it behind its drawings. Written for
   WCAG 2.2 AA and older readers: 18px text, strong contrast, large targets, visible focus, nothing that needs a mouse. */
