The trainer intro was the only enemy send-out path that never set
enemySendingOut, so the front sprite drew at full size the moment the
trainer pic walked off, held through "X sent out Y!", and the grow-in
then played over a mon that had already arrived. Set it with the pic
teardown and clear it with startGrowIn, matching the mid-battle
replacement and the player's own send-out.
Also repairs two parity suites that could not load at all: their game
stubs lacked input.isDown, which battle text has read every frame since
typing started honouring PrintLetterDelay. intro_chrome additionally
pressed A inside PromptText's ProtectedDelay3 hold, which ignores the
button for TEXT_PRE_ADVANCE frames.
The battle intro slide ran at 4px/frame over 40 frames -- twice the
original speed -- and drew the pics in their normal palette instead of
as black silhouettes.
SlidePlayerAndEnemySilhouettesOnScreen scrolls SCX from $90 to 0 at
2px/frame (~72 frames) under the %11100100 silhouette palette, only
running SET_PAL_BATTLE once the pics land. Match that: introSlide starts
at 80 with a 2px/frame offset (80 frames over the full 160px width), and
picImage bakes both pics through PAL_BLACK while introSlide > 0, exactly
like the evolution movie (#279).
parity_battle_intro_chrome waited a hardcoded 45 frames for the slide to
land; bumped to 85 to cover the slower slide.
