/* flocks.live — landing.
 *
 * A paleta não é "inspirada" na marca: são os stops reais que
 * `swatchFromSeed` deriva das sementes do flocks_brand.dart
 * (#4F46E5 primário, #E5484D acento, #6B7280 neutro), por tom HCT.
 * Papéis espelham o AppThemeData: página em neutral.300 (o
 * kShellSeparationShade), cartão em neutral.50, texto em neutral.900.
 * Tipografia é o AppBrandTypography da marca: Space Grotesk no
 * display, Poppins no corpo. Radius coerente com AppRadiusMode.redondo.
