- The view is a raycaster: walls are one tile tall and flat-shaded, there is
  no looking up or down, and everything that is not a wall — bodies, the
  spike, ability zones — is a flat billboard scaled by distance and clipped
  against the walls. It is drawn into an offscreen canvas a fixed number of
  columns wide (`static/resolution.js`: 1280 on a wide window, 960 otherwise,
  never more than the canvas has pixels) and scaled onto the visible one, so
  the frame costs the same on a retina screen as on any other; the crosshair,
  the HUD and the minimap are drawn on top at full device resolution. Columns
  that would draw the same rectangle are batched into one fill
  (`static/slices.js`), and if the frame still runs over 20ms the render
  width drops a rung until it fits (`static/budget.js`). All of that is
  presentation: the simulation and the snapshots are untouched by it.
