lib/savedex.js parses a Generation III save (Ruby/Sapphire/Emerald/
FireRed/LeafGreen): picks the newer of the two save slots, resolves the
rotated section order via each section's footer, and reads the seen /
owned bitfields out of `struct Pokedex` in section 0 (bit dexNo-1, 386
species). Also decodes the trainer name and detects the national-dex
magic byte. Soft checksum check.
Settings > Your data: "Import from a GBA save" — file picker → confirm →
selection.importFlags() merges seen/caught in (never removes). Verified
against synthetic saves (slot selection, rotation, FRLG vs RSE, bit
decode) and end-to-end through the Settings UI.
