/* Low-health desaturation.
   Applied to the WebGL canvas rather than to a HUD overlay, because an overlay
   can only add colour on top and this effect has to REMOVE it. hud.js writes
   --hud-sat (1 = healthy, 0.5 = dead). style.css is read-only, so the canvas is
   selected here by tag; the variable defaults to 1, so with the HUD absent or
   before the first update this rule is a no-op. */
