handoff: address the loading bundles by pak entry, not by is_build ordinal

Browse Source 
The port caught this before writing a name: over the twelve bundles is_build
accepts, ordinals 10/11 are entries 12/15, while ENTRIES 10/11 are the two
splash bundles. A key written from an ordinal names the publisher wordmark as a
loading screen and still validates. Restated in entry space throughout.

So `screen render` is still the reference you diff against, unchanged. **If your

🔴 **Address these by PAK ENTRY, not by `is_build` ordinal.** The port raised
this and it is a real foot-gun: over the twelve bundles `is_build` accepts
(entries 0,1,2,3,4,5,6,7,8,9,12,15) the *ordinals* 10 and 11 are **entries 12 and
15**, while **entries** 10 and 11 are `palogo_sqex` and
`palogo_gamearts`/`seta`/`anima` — the two splashes. A key written `"10"`/`"11"`
from an ordinal therefore names the publisher wordmark and the developer logos as
loading screens, and everything still validates. The loading bundles are
**entries 0, 1, 12, 15** (= build ordinals 0, 1, 10, 11).
**Decoded** — the authors' own element names, straight out of the declaration
table. Every element of all four bundles is prefixed `pgloading_`: the 7-element
pair (builds 0/1) is the plain plate, the 10-element pair (builds 10/11) adds
pair (entries 0/1) is the plain plate, the 10-element pair (entries 12/15) adds
`pgloading_eff00.prm`, `pgloading_loop5.rat` and `pgloading_baseeff.t32` over a
circuit-line background. `DELTASABER / SYLPHEED A.I.` is the caption art on
`pgloading_str.t32`, not the screen's identity.

All eight pairs put exactly one member in each half of `GP_TITLE.p00`, and all
