fix: Bilbo randomness — roll once per tick (#88)

Sound integration points:
- writeCode() -> playClick()
- buyBuilding() -> playBuild()
- buyProject() -> playProject()
- checkMilestones() -> playMilestone()
- showPhaseTransition() -> playFanfare() + updateAmbientPhase()
- renderDriftEnding() -> playDriftEnding()
- renderBeaconEnding() -> playBeaconEnding()
- Game init -> startAmbient() on first user interaction
- toggleMute() -> onMuteChanged() for ambient gain control

All hooks use typeof guard to avoid errors if sound.js fails to load.

+# Dead Code Audit — the-beacon
+_2026-04-12, Perplexity QA_
+
+## Findings
+
+### Potentially Unimported Files
+
+The following files were added by recent PRs but may not be imported
+by the main game runtime (`js/main.js` → `js/engine.js`):
+
+| File | Added By | Lines | Status |
+|------|----------|-------|--------|
+| `game/npc-logic.js` | PR #79 (GOFAI NPC State Machine) | ~150 | **Verify import** |
+| `scripts/guardrails.js` | PR #80 (GOFAI Symbolic Guardrails) | ~120 | **Verify import** |
+
+**Action:** Check if `js/main.js` or `js/engine.js` imports from `game/` or `scripts/`.
+If not, these files are dead code and should either be:
+1. Imported and wired into the game loop, or
+2. Moved to `docs/` as reference implementations
+
+### game.js Bloat (PR #76)
+
+PR #76 (Gemini GOFAI Mega Integration) added +3,258 lines to `game.js`
+with 0 deletions, ostensibly for two small accessibility/debuff fixes.
+
+**Likely cause:** Gemini rewrote the entire file instead of making targeted edits.
+
+**Action:** Diff `game.js` before and after PR #76 to identify:
+- Dead functions that were rewritten but the originals not removed
+- Duplicate logic
+- Style regressions
+
+PR #77 (Timmy, +9/-8) was the corrective patch — verify it addressed the bloat.
+
+### Recommendations
+
+1. Add a `js/imports.md` or similar manifest listing which files are
+   actually loaded by the game runtime
+2. Consider a build step or linter that flags unused exports
+3. Review any future Gemini PRs for whole-file rewrites vs targeted edits
+
+---
+
+_This audit was generated from the post-merge review pass. The findings
+are based on file structure analysis, not runtime testing._
