fix: runestone formula, prestige/transcendence rebalance, exploration fixes, and comprehensive balance audit (#135)

## What changed and why

### Runestone formula (`prestige.ts`)
- Swapped `sqrt` for `cbrt` — much stronger diminishing returns for large gold values
- Added base cap of **200** (→ ~1,125 max with all upgrades at 5.625× multiplier)
- Prevents extended AFK sessions from producing runestone windfalls that allow immediate upgrade purchasing and rapid prestige chaining

### Prestige threshold formula (`prestige.ts`)
- Old: `1,000,000 × 5^n` — exponential, grows impossibly fast, prestige 10+ takes years
- New: `1,000,000 × (n+1)²` — polynomial, peaks at ~1 day/run around P8–10, then gets *easier* as the production multiplier overtakes it
- Removed `thresholdScaleFactor` constant (no longer needed)

### Production multiplier (`prestige.ts`)
- Old: `1.15^n`
- New: `1.25^n` — compounds faster, ensures the polynomial threshold eventually gets easy in the late game

### Boss prestige requirements (`bosses.ts`)
- Rescaled proportionally from 0–88 range to 0–20 range
- The Absolute One now requires prestige **20** (was 88), making transcendence reachable in a few weeks of idle play

### Echo formula (`transcendence.ts`)
- Constant changed from 853 → **224**
- At the target prestige of 20: `floor(224 / sqrt(20)) = 50 echoes` per transcendence (no meta upgrades)
- With all echo_meta upgrades (3.75× total): up to **187 echoes** per transcendence

### Transcendence upgrade costs (`transcendenceUpgrades.ts`)
- Old total: **866 echoes** → New total: **400 echoes** (roughly halved across all categories)
- Apotheosis still requires **all 15 upgrades** purchased

### Balance fixes (closes #141, #142, #143, #144, #145)
- Equipment: `philosophers_stone` click multiplier 2.25→2.5, `crystal_shard` 1.55→1.65 (#144)
- Recipes: added `primal_omega_lens` cross-zone click_power recipe at 1.38× (#142)
- Adventurers: `celestial_guard` base cost adjusted to smooth tier 14→15→16 cost curve (#145)

### Quest reward rebalancing (closes #136, #137)
- Shadow Marshes: buffed `shadow_mere`, `witch_coven`, `plague_ruins` rewards to match combat requirements (#136)
- Astral Void: added gold to `void_rift`, increased rewards across all Astral Void quests (#137)

### Boss reward additions (closes #138, #139, #140)
- Assigned 9 unassigned adventurer-specific upgrades to Crystalline Spire through Eternal Throne bosses that had empty `upgradeRewards` arrays (#140)

### Combat power documentation (closes #153)
- Expanded JSDoc on `computePartyCombatPower` to clarify companion `bossDamage` multiplier behaviour

### Effective adventurer stats (closes #154)
- Added `computeEffectiveAdventurerStats` to `tick.ts` and updated `AdventurerCard` to display effective post-multiplier stats

### Adventurer upgrade timing (closes #158)
- Audited every adventurer-specific upgrade reward — upgrades now land within the same progression window where that adventurer tier is still a meaningful contributor

### Sync and save fixes (closes #147, #148, #151)
- Fixed sync new content count to report only genuinely changed items (#147)
- Fixed signature mismatch after first auto-boss completion (#148)
- Added auto-buy cap (100) on non-max-tier adventurers (#151)

### Auto-adventurer persistence (closes #156)
- Auto-buy preference now preserved across prestige resets

### Broken CDN image (closes #159)
- Uploaded missing `auto_adventurer.jpg` to CDN

### Codex unlock hints (closes #146)
- Locked codex entries now display a hint generated from `sourceType` and `sourceId`

### Exploration bug fixes (closes #160, #161)
- Fixed auto-save race condition discarding exploration materials collected mid-tick (#160)
- Fixed exploration areas failing to unlock when zone was unlocked via boss kill or quest completion (#161)

### Concurrent prestige fix (closes #162)
- Added optimistic locking via `updatedAt` — concurrent prestige requests return 409

### Prestige UX (closes #163)
- Added `reloadSilent` to game context — no loading screen flash after prestige

### Balance adjustments (closes #164, #165, #166, #167)
- Reduced `shadow_mere` CP requirement 5,000,000 → 2,000,000 (#164)
- Buffed crystal drops from Shadow Marshes bosses and quests (#165)
- Increased runestone yield from 10 → 15 per prestige level (#166)
- Daily challenge set always includes a clicks challenge (#167)

### Progression QoL (closes #168, #169)
- Added `computeProjectedRunestones()` and persistent `+N On Prestige` resource bar row (#168)
- Added `enablePrestigeAnnouncements` setting per player (#169)

---

## Comprehensive balance audit (closes #187, #191, #192, #193, #194, #195, #196, #197, #198)

### Crystal economy fixes
- Zeroed crystal rewards for all Zone 7+ boss drops (Celestial Reaches onwards) — crystals are an early/mid-game currency and should not flow freely into the endgame (#187)
- Zeroed crystal rewards for all Zone 9+ quest rewards (Infernal Court onwards) — same rationale (#191)

### Achievement additions and fixes
- Added quest milestone achievements at 75 quests (10,000 crystals) and 100 quests (15,000 crystals)
- Added boss milestone achievement at 50 bosses (15,000 crystals)
- Added prestige milestone achievements at P50, P100, P150, P200 — rewarding **runestones** rather than crystals to match the late-game economy
- Added gold milestone achievements through 1e90 gold earned
- Fixed `quest_eternal` condition from 122 → **112** (actual quest count) — was permanently impossible (#197)
- Fixed `fully_equipped` condition from 65 → **78** (actual equipment count after new items) (#197)
- Fixed `devourer_slayer` description to remove incorrect zone reference

### Upgrade balance
- Fixed Essence Guild multiplier 1.5× → **2×** — was identical to the cheaper Merchant Alliance for 5× the cost (#194)
- Raised Void Ascendancy crystal cost 10M → **50M** — was trivially cheap compared to the parallel Celestial Mandate upgrade (100B essence + 50T gold) (#195)
- Fixed Sunken Temple quest rewards (gold 2M → 60M, essence 1,500 → 25,000, crystals 75 → 400) — was rewarding less than its easier prerequisite Witch Coven (#193)

### Equipment balance
- Buffed Eternal Prism stats to click 5×, combat **3×**, gold **2.5×** — was only marginally better than the free Eternity Stone boss drop for 100M crystals (#196)

### Missing content
- Created **13 missing equipment items** for Zones 15–18 (primordial_chaos through the_absolute) that were referenced by late-game boss `equipmentRewards` arrays but never existed in `equipment.ts` (#198):
  - `chaos_mantle`, `titan_core` (Primordial Chaos)
  - `expanse_blade`, `void_armour_mk2` (Infinite Expanse)
  - `cosmos_blade`, `reality_plate` (Reality Forge)
  - `maelstrom_edge`, `cosmic_plate` (Cosmic Maelstrom)
  - `primeval_blade`, `ancient_aegis` (Primeval Sanctum)
  - `absolute_blade`, `eternity_plate`, `omniversal_core` (The Absolute)
- Stats scale from combat 14× / gold 9× (Zone 15) up to combat 28× / gold 20× for the final boss drops

### Type system
- Extended `AchievementReward` type to support `runestones` field
- Updated tick engine achievement processing to award both crystals and runestones

---

## Target progression timeline (optimal play, ~16h/day idle)
- First cycle to P20: ~375h (~3.3 weeks)
- Each subsequent cycle gets faster as echo upgrades boost income/combat/threshold
- Expected **~5 transcendences** before apotheosis at 50–187 echoes/transcendence
- **~6 months** to apotheosis for a dedicated player

## Test plan
- [ ] Lint, build, and test pipeline passes (100% coverage maintained)
- [ ] Prestige threshold at P0 is still 1,000,000 gold
- [ ] Prestige runs feel ~1 day long around P8–10 and get easier after
- [ ] The Absolute One is locked until prestige 20
- [ ] Transcendence at P20 awards 50 echoes (no meta upgrades)
- [ ] All 15 transcendence upgrades cost 400 echoes total
- [ ] Bosses in Zones 7+ drop 0 crystals; Zones 1–6 retain crystal drops
- [ ] Quests in Zones 9+ reward 0 crystals; Zones 1–8 retain crystal rewards
- [ ] Sunken Temple rewards more gold/essence/crystals than Witch Coven
- [ ] Essence Guild gives 2× income (stronger than Merchant Alliance 1.5×)
- [ ] Void Ascendancy costs 50M crystals
- [ ] Eternal Prism stats are click 5×, combat 3×, gold 2.5×
- [ ] Late-game bosses (primordial_titan through the_absolute_one) drop equipment on kill
- [ ] `quest_eternal` achievement requires 112 quests
- [ ] `fully_equipped` achievement requires 78 equipment pieces
- [ ] P50/P100/P150/P200 prestige achievements reward runestones
- [ ] Adventurer cards show effective post-multiplier stats
- [ ] Exploration areas unlock correctly when their zone is unlocked
- [ ] Concurrent prestige requests return 409
- [ ] No loading screen flash after prestige
- [ ] Daily challenge set always includes a clicks challenge
- [ ] Resource bar shows `+N On Prestige` runestone preview

-
-## Phase 4 — API changes
-
-- [ ] Add `inGuild` to Prisma `Player` model → update `initialGameState` if needed (already done in #134 — verify migration)
-- [ ] Update Prisma schema: no DB changes needed (expansion state is inside the `GameState` JSON blob)
-- [ ] Update `initialState.ts` to include `expansions: {}` in `initialGameState`
-- [ ] Update `sync-new-content` debug route to inject/patch vampire expansion content when expansion is unlocked
-- [ ] Add vampire-specific unlock trigger: when base-game apotheosis count ≥ 1, set `expansions.vampire` to `initialVampireState()` and `unlocked: true`
-- [ ] Update the load endpoint to pass expansion state through to the client
-- [ ] Ensure prestige/transcendence/apotheosis routes only reset state for their own expansion (base game routes must NOT touch `expansions.*`)
-- [ ] Add vampire prestige, transcendence, and apotheosis routes (mirrors of base game routes, scoped to `expansions.vampire`)
-- [ ] Grant `Eternal Sovereignty` role (ID: `1486144657023959180`) on vampire apotheosis
-
----
-
-## Phase 5 — Frontend changes
-
-### Expansion switcher
-- [ ] Add expansion toggle buttons below the Early Access warning in the sidebar
-- [ ] Always render all expansion buttons; disable any where `unlocked !== true`
-- [ ] Active expansion stored in React state (not game state); defaults to `"base"`
-- [ ] Switching expansion updates which data the UI panels display
-
-### Resource bar
-- [ ] Show ALL currencies from ALL expansions as separate labelled lines
-- [ ] Vampire currencies use distinct icons/colours (crimson tint for blood, etc.)
-- [ ] The "expand" button label shows the gold-equivalent currency of the active expansion
-
-### Thematic UI
-- [ ] When vampire expansion is active, swap labels: gold → Blood, essence → Ichor, etc.
-- [ ] Apply `.vampire-mode` CSS class to game container when vampire is active
-- [ ] Vampire colour palette: deep crimsons (`#5C0A1A`), rich crimson (`#C41E3A`), blacks, desaturated purples
-
-### Tick engine
-- [ ] Update `apps/web/src/engine/tick.ts` to compute passive income for all unlocked expansions every tick (not just base game)
-- [ ] Offline income calculation must also cover all expansions
-
-### Profile
-- [ ] Profile panel: tab stats by expansion (base game tab + one tab per unlocked expansion)
-- [ ] Show correct thematic prestige/transcendence/apotheosis badge names per expansion
-- [ ] Lifetime stats (gold earned, clicks, etc.) tracked separately per expansion
-
-### About / How to Play
-- [ ] Update `aboutPanel.tsx` `HOW_TO_PLAY` array to document the expansion system
-
----
-
-## Phase 6 — Tests & CI
-
-- [ ] Unit tests for all new data files (at minimum, validate structure/required fields)
-- [ ] Unit tests for `initialVampireState()`
-- [ ] Tests for vampire unlock trigger route
-- [ ] Tests for vampire prestige/transcendence/apotheosis routes
-- [ ] Tests for updated tick engine (expansion income)
-- [ ] Maintain 100% coverage on `apps/api` and `packages/types`
-- [ ] Full pipeline: lint → build → test passing before PR
-
----
-
-## Phase 7 — Final
-
-- [ ] Delete `img/vampire/` directory before committing
-- [ ] Update `MEMORY.md` with new content counts
-- [ ] Open PR → request review
