Seam Craft — render prerequisites for scene-to-scene transitions

This is the

render-correctness doctrine

for PLV scene-to-scene seams: the

prerequisites and master-timeline mechanics that make any transition composite

correctly, independent of which specific transition is chosen. The per-transition

catalog (crossfade, push-slide, zoom-through, cut-the-curve, …) lives in the

transition registry — this page is the doctrine that sits underneath all of them.

The transitions this doctrine governs are

Tier-B-ready

pure transform / opacity / filter on the two scene clip wrappers (

el-

), no injected overlay DOM, no per-scene cooperation. Overlay families (staggered blocks, blinds, light leak, grid dissolve, page burn) and shader transitions are deferred to later phases.
