- Level-up build-route advisor (src/features/characters/sheet/LevelUpAdvisor.tsx +
useLevelUpAdvisor): ~4 system-aware routes plus a custom one; choosing a route
expands it into concrete next-level steps. AI when configured, deterministic
fallback (src/lib/assistant/levelup.ts) otherwise. Embedded in the existing
HP-only LevelUpModal, which stays primary.
- Level-up prompts/schemas added to prompts.ts (buildRoutes/buildSteps), each
leading with the system constraint + class + next level.
- Campaign Insights section on the Assistant page renders deterministic themes,
with an optional 'ask the assistant to expand' affordance when AI is on.
levelup + prompt unit tests (4 routes both systems, system vocabulary, custom
route); e2e for the deterministic route→steps flow and the insights section.
