/* Credenda landing page (Task 1.11)
 *
 * Buyer-facing styling for credenda.io. Distinct from the dev /
 * dashboard skeleton in ../styles.css, but reuses its CSS custom
 * properties (--accent, --muted, etc.) so the brand reads as one
 * surface end-to-end.
 *
 * The visual language is: serif marketing display + grotesque body,
 * generous vertical rhythm, restrained accent use. No imagery, no
 * gradients, no SaaS-template flourishes — buyers in this segment
 * (mid-cap CFOs, treasury consultants) are allergic to that.
