/* ==========================================================================================
   The National Cyber Security Month landing page — a temporary face for /home.

   Loaded only while CSAT Settings has it chosen (www/home.html). Every rule is scoped to `nc-`
   classes or `body.page-ncsm`, so nothing here reaches any other page; the palette the other
   pages wear while this is the site's face (`theme-ncsm`, `palette-ncsm`) lives in site.css.

   It is built the way the Awareness Month page is: the site's own tokens redeclared on body, so
   the shared buttons, eyebrows, footer and closing ask take the month's colours without being
   restyled; hairlines rather than cards; one accent. The accent is the logo's blue, and the logo's
   whole gradient — blue, violet, coral — is kept for the few marks that carry it: the rule under
   the date, the four weeks, the circuit drawn faint behind the hero, the numbers and the ask.
   ========================================================================================== */

/* ---- the palette ---------------------------------------------------------------------------
   tokens.css turns the root dark on a dark system; this page opens in the theme the month is set to
   (Site design, csat/brand.py) whatever the system says, and after that in the one the visitor
   picks from the header's switch, like the other month pages */
