/* Night Shift Scarlet: shared styles for the hand-written root pages
   (index.html, support.html, privacy-policy-pulseu.html).
   Tokens, nav, footer, buttons and the title band live here so the three
   pages cannot drift. Page-specific rules stay inline in each page.
   Generated event and hub pages use web/index.css, not this file. */
