/* SecureSend visual system: "Zero Trust Garage" terminal / SOC-dashboard theme.
   Near-black navy surfaces, a single phosphor-green accent, monospace ALL_CAPS
   labels, sharp corners, thin translucent borders, restrained green glows.

   Ported from a Tailwind reference to hand-written CSS: the app is static HTML
   with a strict CSP (style-src 'self'), so there are no utility classes and no
   inline styles. Class names are unchanged from the previous stylesheet because
   the page JS toggles them (is-hidden, is-active, tag, btn, hint, field...).

   Prose uses the humanist sans; mono is reserved for labels, nav, buttons,
   stats, chips and code. Fonts are self-hosted so the CSP needs no third-party
   origins. Presentation only. */
