 *  Brand-expression surface (design-system §12 "rotor = telemetry"): it

 *  aerial-survey image overlay that the component --accent/surface aliases
 *  do not cover. Per design-system rule §1, those brand colors are declared
 *  here as FILE-PRIVATE tokens in this scoped :root (the only place hex is
 *  allowed in a pages/*.css file); every rule below consumes them via var().
 *  All classes are `ls-` prefixed and scoped under `.ls` so nothing collides
 *  with the global Bootstrap/Datta or design-system component styles.
