/* Standalone manager login — locked R5 brand, no dashboard chrome.
   This shell intentionally does NOT load the R5 CSS payload (see
   docs/LIVE_R5_SHELL_LOCK.md); these custom properties are local mirrors
   of the canonical values in dashboard/static/vnext/r5/css/tokens.css,
   snapped to the nearest exact R5 token so brand color stays a single
   source of truth without adding the R5 stack's weight to /auth/login. */
