The technique catalog: five velocity-matched SEAMS (zoom-through, INVERSE zoom-through, cut-the-curve, waterfall cut, rack-focus blur-cut) plus the two in-scene techniques — waterfall ENTRY (staggered arrival cascades for title cards / segment openers) and the nudge curve (slow-fast-slow three-phase group slides). Covers partial-travel (~12% of frame) velocity matching via mirrored power4 eases, the Z scale-sign rule, size-scaled blur (10px text / 18-20px full-frame), word-by-word staggered cuts, cascade pacing by element weight, and the 10/65/25 slide ratio. Read before authoring any transition, text-beat handoff, kinetic text entry, or group reposition.

Documentation
README · ~11 min readCut the Curve — the technique catalog
Five SEAM techniques, one principle: cut at peak velocity, match direction and speed
on both sides of the cut — plus the two in-scene techniques (§6 arrivals, §7 slides).
The seam LAW — vector law, the current, the ledger, the Seam Gate — lives in
motion-doctrine; read it first. This skill is the parameters and mechanics.
