/* Cow Digital OS — calm, readable, phone-first. Platform design tokens live here; a customer's own brand colours
   only tint their logo/brand previews, never the app chrome (platform and customer branding stay separate). */
/* Cow Digital palette, from the logo: indigo → violet → magenta → apricot, with calm greys.
   Light: soft lavender canvas, white cards. Dark: deep ink-violet, never pure black. A business's own main colour
   (My brand) can replace --accent for its team; the gradient stays Cow Digital's. */
