/* 15 Oct 2026: neutral black and charcoal (was navy #0A0E1A / #121829) with a soft grey-white glow instead of the indigo one -
   the user asked for the theme's black and grey on the session-timeout, 404, error and no-access pages */
/* =====================================================================================================================
   OneBook status pages - session timeout (SessionExpire.aspx), not found (FileNotFound.htm), no access (NoAccess.htm),
   something went wrong (GenericErrorPage.htm). The sign-in page's "trade desk" language (onebook-trade.css): ink field,
   one indigo accent, Inter Tight + IBM Plex Mono, sharp corners, the faint grid and a departure-board panel.
   Self-contained: the static pages must render even when the application itself is failing.
