osmose.forcing.percid_habitat¶
Real perch/pikeperch habitat as a BINARY thin-littoral set: a cell is habitat iff a meaningful fraction (>= tau) of it is shallow littoral AND salinity permits. Binary (not fractional) so the habitat SET/AREA genuinely shrinks and is read unambiguously by the engine’s map semantics. Salinity gate on spawning; relaxed ceiling on adult/juvenile. Land -> -99.
