/* SUAAMS site: suaams.com.ng, /get and the privacy policy.
   Plain CSS, no build step: edit and upload.

   The site lives in the app's own world, "Midnight Instrument" (DESIGN.md):
   near-black ground, graphite panels, IBM Plex Sans for words and Plex Mono
   only for what a machine says (the check-in code, times, masked IDs,
   readouts), and one accent, Contactless Indigo. Every value below is the
   app's (AppTerminal.dark / .light, app_theme.dart), so the screenshots on
   the page sit in their native colours. Dark is the default; light follows
   the visitor's system setting, like the app.

   Green means "present" and nothing else, always with its label. */

/* ---------- Fonts ----------
   Self-hosted, cut down to Latin (about 70 KB for all five), from the
   same TTFs the app bundles. Not Google Fonts: on slow campus Wi-Fi a
   third-party font request is the slowest thing on the page, which is
   the same reason the app bundles them. */
