• LZ4 packs for games whose ampr_emu is missing or too old. When the check finds a game
  that reads through AMPR but ships no fakelib/libSceAmpr.sprx, or one that predates asset
  packs, the LZ4 option now offers "Put ampr_emu 0.4.2.1 into the image": the engine fetches
  drakmor's release once (checked against a known digest, never bundled) and writes it into
  the image, keeping the game's own copy beside it as libSceAmpr.sprx.orig. This is the
  runtime gap behind #449.
• A game that does not use AMPR is told so. The LZ4 option explains that nothing in such a
  game could serve asset packs, and points at .ffpfsc, which ShadowMount+ decompresses for any
  game, instead of just refusing.
