Claude (auto-RE) 9a86a09f8d re: ui — the RATC bundle header is the screen's element declaration table ...

u32 count at 0x14, then fixed 60-byte entries of [name | 4 flag words | pivotX |
pivotY | 0]. The table lists both .t32 sprites and .rat records, so it is the
screen's element list.

Verified: for all 7 .t32 entries in the tutorial pause bundle the declared pivot
is exactly half the decoded texture's dimensions, 7/7 with no mismatch. That also
settles what the pair at 0x50/0x54 of a .rat record is — a .rat simply opens with
one of these declarations.

The language split is visible inside one bundle: the English build's .t32
declarations carry correct English pivots while its .rat declarations carry
Japanese-derived ones, so the sprite table is regenerated per language and the
layout layer is inherited from the Japanese master.

Adds tools/re-capture/ratc_decls.py (parse the table, check pivots against the
decoded textures).
