/* ShotPro — Public (pre-login) marketing brand layer.

 * "Restrained Editorial Ink-Violet." This file is loaded ONLY by the public
 * marketing layout (templates/layouts/public.templ). Every brand token is
 * scoped under `.sp-public`, so the authenticated app shell keeps its own
 * steel-blue/Inter chrome untouched.
 *
 * Three faces carry the register: Prata (display serif), Inter (UI sans),
 * JetBrains Mono (eyebrows / metadata / crop-mark captions).
 *
 * Named rules:
 *  - THE RARE ACCENT RULE: --brand marks decisions and state, never decorated
 *    surfaces. If every card is violet, nothing is important.
 *  - THE LOW-CHROMA RULE: no saturated gradients, no neon glow.
