The whole isolate's ceiling, the one the platform enforces.
RECYCLE_ABOVE_BYTES compares wasm linear memory only, so it fires too late (the 128 MiB covers
the JS heap too). 124 MiB holds 4 MiB back for one workload landing above a growth rung.
Separate from it because an operator who set that set a linear number, and reading it as a total
would recycle on every request.
