-- Comprehensive test suite for authentic FRLG Pokédex subsystem in Game 3.
-- Tests:
-- 1. Offline data extraction verification & manifest loading.
-- 2. 9 Habitat categories (Grassland, Forest, Waters-Edge, Sea, Cave, Mountain, Rough-Terrain, Urban, Rare).
-- 3. 6 Sorting orders (Numerical Kanto, Numerical National, Alphabetical, Type, Lightest, Smallest).
-- 4. Wild encounter area lookup & route marker coordinates (Kanto & Sevii Islands 1-7).
-- 5. 2-page description flavor text (FireRed & LeafGreen), height/weight metrics, and scaling offsets.
-- 6. Interactive UI state machine transitions across all 8 sub-screens.
