TaikoZhongandClaude Fable 5.1 4d3127d9ea Replay the cabinet's add-blended light effects as additive
The exported clips and backdrop movies were drawn source-over everywhere, but the
cabinet places a number of glow layers with its add blend mode: the lantern glows
of the lower backdrops (bg_nomal_a_01..05), the crown's radial burst, the score
rank plate's effect copy, and the full-combo / donderful letter glows.  Drawn
source-over, those textures show up as dark or grey patches.

- movie_export / clip_export record the placement's blend mode (`blend = 8` on a
  backdrop leaf, an 8th row value on a clip leaf; the root placement's mode is
  folded into its group), and bg_anim / clip_player / ending draw such leaves
  with blend = "additive".  Data re-exported; only the blend field changed.
- result_crown: the burst copies draw additively; the crown_loop shine sweep is a
  plain white polygon on the cabinet, so gleam frames 0..2 are white now instead
  of the atlas colour they were exported with.
