Credibility pass: comments say what the code can't, and the seams are gone

Engine: pit-rim exits live in one helper (pitRimExits) shared by the
resolver and the automaton; chargeReach names the six-stride cap; dust
sight is inDust + dustAtEnd; PushPending is exported once; the force-field
counter builds its events in one list; drawUnderSlowDeath says what it
draws under. Test groups are named for the rule they pin, not the
revision that introduced it.

Client: one smoothstep; one edgeScar per battle-scarred edge; one
board-zone rule (which also seats the caption strip on phones); the
compass names live in SIDE_NAMES; net.flash() is the one toast; MediaQuery
replaces two hand-rolled matchMedia listeners; sprites carry their sizes
as plain numbers and their CSS in one rule each; canvas helpers are
formatted like the rest of the tree. Comments that told how a cel or a
fallback used to look now say what it draws. The actions-over notice no
longer blames a pickup when slime ended the turn.

Server and ops: dataRoot() is the one data directory; headlineOf builds
its deeds without a cast; the rollup and skills read the same way the
code behaves.
