/* RingSafe AI marketing site styles.
   Palette: "Ironclad" -- graphite + brass/gold, sampled directly from the
   RingSafe shield logo (background #161B21, gold #C6883A). Dark is the
   default theme; light is available via the toggle. Red is reserved
   strictly for an actual risk/scam signal -- never a plan, button, or
   brand highlight -- unlike PhoneShield.ai's red/black featured card. */
