/* app.css - Steward's look: modern and quiet, with a nod to DEC and OpenVMS.

   Light: cool slate with a deep burgundy accent, the colour of DEC's corporate era.
   Dark:  a VT220 amber phosphor on near-black; the glow is kept to terminal elements.
   Monospace and upper-case tracking stand in for DCL; privileges and identifiers
   are keycaps from the LK201; messages read like OpenVMS messages
   (%STEWARD-E-SIGNIN, ...). Nothing here reproduces a DEC or VSI mark. */
