/* ---------------------------------------------------------------------------
 * Hold the Line — the playable hero.
 *
 * Two palettes meet here on purpose. The chrome around the screen (HUD, build
 * panel, overlays, scoreboard) is drawn from the studio's own tokens so the
 * game sits *in* the page rather than on top of it. Everything inside the
 * canvas is CropCorp's own palette, painted in JS from CCBlocks.h.
 *
 * Mobile first: the build panel is a horizontal strip under the screen and
 * moves to the left of it from 720px up. Everything is scoped under .htl.
