Added an interior draw-budget sweep to flags_check.py (decision #2): enter all 9 shop types,
assert <=350 draws/room, dig on so it also confirms C1's batching kept ?dig=1 riffling.
The sweep caught a real bug in interior_mode.js (F-owned): the interior/dig render never called
renderer.info.reset() while the shell runs autoReset=false (for the composer), so
renderer.info.render.calls ACCUMULATED every frame — inflating any interior draw read (and the
HUD were it shown). Fixed: reset per interior frame before both the dig and the walk render.
True per-frame result after the fix: all 9 room types <=350 draws (worst dept 96) — C1 batching
(35981ad) verified. flags_check GREEN (regression + interior budget + 4 flag smokes + all-on combo).
