Each cast becomes one event: who used which ability, when its first actor
appeared. A follow-up actor (where a thrown smoke lands, what a trap sets
off) joins the cast before it, as do actors that appear together. Chips
above the killfeed choose Kills, Spike and Abilities; the scrubber marks
the same events, ability uses as small dots in the caster's colour. The
choice lasts while the app is open, and abilities start hidden.
