// asset_io — the one portable asset-read point.
//
// The standalone libs (libgr2, formats, mtproto, mtpack) keep their raw
// fopen/ifstream `*_path()` entry points for the non-Godot CTests. Every read
// from the *running extension* goes through here instead, so it works for:
//   - res://  (loose files in dev, PCK on iOS/Android read-only bundles)
//   - user:// (extracted cache)
//   - absolute OS paths (dev: AssetRoot points at mtgodot-poc/assets/)
// godot::FileAccess handles all three transparently.
//   - pack://<40250 path> (e.g. pack://locale/en/item_proto, pack://d:/ymir work/pc/...): the 40250 packs,
//     read through the ported CEterPackManager once Metin2Pack.initialize(<Client dir>) has run
//     (platform/PackBackend.h). The path after pack:// is passed as UTF-8.
