feedback7: merge fb7-loadout — per-operator 潜能 (1–6) and 练度 (未精英化 / 精英1 / 精英2 / 精英2 Lv.60) set in 干员调配, defaults 潜能 6 and 精英2 Lv.60 (the owner's decision of 2026-10-08); PR #301 ported as one aligned list; #398 the skill frame, #400 REA-Y's heal text

- Conflicts (the branch started at ae22335c): the four i18n packs (union of keys), game.js DetailPanel props (ops + the
  voices' voice=true), detailPanel.js resolveDetail (cultOpts + the voices' tap), match/views.js (both helpers),
  docs/PLAYING.md and design/network.md merged line by line against the base. test/match/bosshp.test.js's ATK formula
  now includes the unit's 练度 multiplier (cultMul).
- Grok review: MERGE AFTER FIXES — the note and the module card at the set potential fixed on the branch.
- Golden: every owned operator ×1.1 ATK / DEF / max HP by default — roster 49, bonds 46, fields 22, matches 18, diy 134
  (stand-in battles and prototype picks unchanged). Broad node --test 5666 (0 fail after the bosshp formula; 2 skipped);
  lint 0 errors; typecheck; i18n strict clean (1152 msgids).
