   linkcouncil.ai — design/"Website frame.dc.html" and design/"Website hero demo.dc.html".
   Values mirror src/ClientUi/wwwroot/nocturne.css (Nocturne dark, Matins light), so the site and the app read as one
   product. Dark first; Matins where the reader's system asks for light. System fonts only: no web fonts, no CDN.
   No page sets a style attribute: the Content-Security-Policy allows this file's styles and nothing inline.
   The faintest text is text-muted, which passes AA in both themes; text-faint is never used for text here.
