/* aiBridge - single stylesheet.
 *
 * The look is modelled on the piofin.ai landing page: one near-monochrome palette,
 * a single blue accent, sharp 4px corners instead of soft ones, very generous
 * vertical rhythm between sections, small uppercase eyebrow labels above each
 * heading, and big quiet numbers for the figures. The brand's violet survives only
 * in the footer gradient.
 *
 * Type is Geist where the visitor can fetch it, with the system stack as the
 * fallback so nothing depends on the network.
