Spectator/guest visuals now use a deterministic cool-palette per handle instead of flat gray — hue range is constrained to 170°–319° (cyan, blue, violet, pink) at moderate saturation and high lightness, so anon watchers read as ghostly/icy and are still individually distinguishable. Refactor: extracted handleHash() + hslToRgb() so handleColor (full hue spectrum, vivid) and specColor (cool half, ghostly) can share the same math. HUD: rename the 'watchers' line to 'specs' (short for spectators). Minimap dots for specs are now 2×2 in their own cool color instead of 1×1 flat gray.
