/*
  thecogquest.com. One screen, like the game's title screen: a robot town going about its day fills
  the window, and the game's own menu panel sits over it. The look is the game's (the owner,
  2026-10-14: "earthy", "feel free to use the game style"), with its colours taken from the title
  screen's panel. The pack's own font and panel pictures are never served (Gowl's licence); the
  panel is drawn here in CSS, the lettering is Pixelify Sans, and the logo is a picture the game
  drew of its name. DESIGN_BRIEF.md has the reasons and the overrides of the Etti rules.
