// MobileGL believes it has already made legal came back non-success, which is a
// should-never-happen state, not an expected failure mode a user hits. Those fast-fail loudly
// and keep saying so - the log-quietness rules that latch W/E cover expected failures (driver
// capability gaps, app misuse), not broken internal invariants. MOBILEGL_ASSERT below traps in
// a DEBUG build; MGLOG_F is what makes the same condition visible in an INFO test run, where
// the assert is compiled out by contract.
//
// A soft, recoverable failure must therefore NOT be routed through VK_VERIFY. Check the
// VkResult directly and report it with MGLOG_E_ONCE - see VkTextureManager::SyncTextureResource,
// where a driver legitimately refuses an image the format pre-check accepted.
