CI / build + unit + e2e (pull_request) Successful in 2m38s
Production freeze reported after the v0.9.3 (#21) deploy: every API route hung and all panels stayed at LOADING. Root cause was not the #21 layout (verified healthy across all 7 tabs/viewports) but makeName's unbounded rejection loop over a finite 16x8=128 system-name pool — once a save grew past ~128 systems, any jump into an undiscovered system spun forever on Node's single thread (sql.js is synchronous), blocking the whole process. makeName and makeCrewName now fall back to numbered variants ('Kepler Drift 2') once their pools are exhausted, so they always terminate.
