/* NtfsForge · ntfsforge.bytehavenstudios.com
   One stylesheet for every page. Shell and class vocabulary cloned from driveforge-web, then re-dressed in
   NtfsForge's own look: the navy-ink ground, azure for the one primary action, teal for ready and safe,
   amber for Pro, hairline cards, Geist throughout (sentence-case labels, as the app since s104).
   Every colour below is a token from the app, never invented:
   apps/ntfsforge/app/src/main/java/.../ui/Theme.kt DarkBrand (and launchkit.yml → brand:), which is the
   studio design language (branding/design-language.md).
   No JavaScript anywhere on this host (CSP script-src 'none'); everything below is CSS-only. */
