/* ============================================================================
   ORGANIC MACRO FX — Brood ichor / bile / violet-black fluid
   ----------------------------------------------------------------------------
   One hit is one animated splash plus one optional wet stain. One death adds
   no more than one extra vapour lobe, for a hard three-layer ceiling. The
   authored 4x4 sheet carries internal droplets as one connected silhouette;
   this module never expands it into a point spray or a pile of glow quads.

   ichor pools: a death or a bio seep can leave one persistent pool — a fourth
   kind that replays the same authored spread sheet over ~20 s at a larger,
   darker, lower-alpha scale, so ground the Brood bleeds on stays visibly
   claimed for a whole engagement instead of evaporating in a second. The pool
   is still one billboard per event with a hard count cap, and it inherits the
   civic rule: no terrain deformation, no crater, no burn record.
