/* ============================================================================
   MachiNation — support/marketing website styles
   Independent from the application CSS (js/… app is untouched). Reuses the
   MachiNation brand palette (navy / brushed-steel / TiN-gold) so the site
   reads as part of the same product family without copying the app's UI.
   Plain CSS, no framework, no build step. Light by default; a dark variant
   follows the visitor's OS preference via one variable override block.
