- memory_monitor: extract kOneGB and kFallbackRAM constants from 6 duplicated 1024*1024*1024 expressions; name kFieldPrefixLen for /proc/meminfo "MemAvailable:" offset (was bare 13) - camera: add why-comment on projection matrix jitter — column 2 holds NDC x/y offset for TAA/FSR2 sub-pixel sampling - movement_handler: name kMaxTaxiNodeId (384) with why-comment — WotLK TaxiNodes.dbc has 384 entries, bitmask is 12 × uint32
