The animation-slice note mis-called the SC0000 opening 'immediate-mode slot-0
blits', inferred from our own gfx oracle (which mis-reported slot 0). Verified from
native code + raw bytecode: draw-texture (0x1fb) -> gfx_object_bind_draw@0x47e870
binds a RETAINED object by handle (stores the slot INDEX, a live per-frame ref, not
a snapshot). The opening is a sleep-paced sequence of retained objects with distinct
handles + per-object working slots (CG loader: handle=CG_array[G[0x62450]] INIT2
array, slot=G[0x62452]). Our VM collapses the paced sequence -> only the final state
shows -> needs frame-pacing (scene-coroutine/sleep), not this alpha channel.
engine-re.md: new 'opening render path is RETAINED' subsection. Ghidra: annotated
gfx_op_0x1fb_draw_bind (gfx_object_bind_draw already documented retained).
