   ASTRACAT Billing — design system.
   Stripe-inspired: light, airy, thin borders, small radii, restrained accent.
   Branding (app_settings BRAND_COLOR / BRAND_COLOR_ACCENT) flows in through
   --brand-color / --brand-accent, so the whole UI re-skins from one setting.
   Everything else is a token; never hard-code a hue in a component.
   Rhythm scale: 4 8 12 16 20 24 32 40 48 (px).
