MorphSurface refresh: first-morph flash fix + anchor/absorption/spring props#10
Merged
Conversation
…nd spring props - Fix one-frame flash on every open flip: declarative path/speculars now track the current spring frame mid-morph (not the target scene), and the static-scene resync effect is guarded by a synchronously-set ref - anchor="top" pins the top edge so the panel pours downward from the pill - absorption="pull" moves satellites at full size and swallows them at the edge (radius derived from travel, so drops re-emerge on close) - bodySpring/satelliteSpring overrides, resolved live via refs - Showcase page: anchor/absorption/spring-preset controls, honest snippet Claude-Session: https://claude.ai/code/session_01EsufuYzyhES9JwrhNz34qC

The parallel refreshes (PRs #10-14) grew the measured core bundle from 12.39 kB to 15.18 kB while the pin stayed at 14.9 kB — each branch fit alone, the merge result didn't. Re-pinned at +20% headroom per the documented convention. Claude-Session: https://claude.ai/code/session_01CFzWWbVjWefJo5At65oS3p

Summary
openflip: the declarativepath/specularsprops jumped to the target scene before the spring loop took over (and a resync effect with a stalesettlingflag did the same via the imperative handle). Declarative props now track the current spring frame mid-morph; the resync is guarded by a synchronously-set ref.anchorprop:"top"pins the top edge so the panel pours downward out of the pill (faces reposition to match). Default"center"unchanged.absorptionprop:"pull"moves satellites at full size and swallows them over the last stretch of travel (radius derived from position, so drops re-emerge on close). Default"shrink"unchanged.bodySpring/satelliteSpringoverrides, resolved live via refs so preset switches apply to the next morph.No
