paper-cinder-transition

Change between pages, chapters or scenes with a paper-burn transition, a ragged ember line that sweeps across the frame, chars the old page ahead of it and reveals the next scene live behind it, written as one WebGL composite pass over a frozen frame and a scissored live scene. Covers the front's silhouette, the luminous ember gradient with a beading gold thread, torn porous charcoal that is alpha-masked, baked noise, finite-difference slopes, the 0.75-scale live scene, sweep direction, timing, reduced motion and visibility pausing. Use for a burn transition, paper burn, cinder wipe, chapter change by fire, charring page reveal, burn-away section change, ember dissolve, or when a fade, slide or generic dissolve between scenes reads as cheap.
