31 tests in test/, run in a plain Node env with a tiny localStorage shim (no jsdom — its Node-22.4 transitive-dep breakage isn't worth working around for logic tests): - type-chart: modern effectiveness, dual-type stacking, and the era rules (no Fairy pre-6, Steel resists Ghost/Dark pre-6, the Gen 1 Ghost→Psychic and Bug↔Poison quirks). - damage-calc: nature multipliers, the Gen 3+ stat formula (Garchomp reference values), STAB/effectiveness/immunity, pre/post-Gen-6 crit. - savedex: a synthetic Gen 1 SRAM (bitfields + checksum) round-trips; checksum-mismatch and size guards. - selection: normalizeSelection v2→v3 migration, per-game isolation, global favourite, stats vs statsNational. - pokedex-resolver: prettify, dex resolution against a mini snapshot. `npm test` wired into CI after format:check. Also: docker-compose host port 8080 → 4753 (README updated). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017Ve7HLspzeG2xDPtJQ8vmu
