/* Mission-console palette. The subject is rocket telemetry, so the page
   borrows from instrument displays rather than a generic dashboard: a deep
   navy ground with a slight blue bias in every neutral, phosphor cyan as the
   working accent, and amber reserved for the rocket itself. Balloon magenta
   and pop red are the environment's own colours (balloon_world.py:810), kept
   so the 3D view and the tables speak the same language. */
