//! WMO MLIQ liquid-surface build — byte check against Stormwind's canals (the reference building

//! for WMO-embedded water; its city is one 306-group WMO, 22 of whose groups carry `MLIQ`). Pins

//! the SMOLiquidHeader decode, the `xtiles = xverts − 1` grid, the per-tile hole nibble (`0xf`), and
|
||
//! the lake_a (nibble 4) type resolution. Skips when the client isn't present.
