/* =============================================================================
   NAV.CSS — the site header and navigation
   -----------------------------------------------------------------------------
   Newspaper masthead logic: white paper, a hairline rule, one red. Every colour
   comes from the tokens in global.css, so retuning the site retunes this too.

   NOTHING HOVERS BLUE. Astra's defaults are overridden on purpose; every
   interactive state here lands on the Druthers red.

   No JavaScript. The mobile panel opens with a checkbox, so it works before any
   script loads and if scripts fail entirely.
