+###  🐾 What is petpet?
+
+petpet is a desktop companion that quietly listens to **Claude Code / Codex / OpenCode / Aider** — and more providers landing soon — then turns your real AI usage into the pet's growth. Code seriously, your pet thrives. Idle, it sleeps.
+
+<div align="center">
+  <img src="assets/screenshots/pet-hover.png" alt="Live pet — hover reveals name, level, XP progress bar, and the upcoming stage" width="380">
+  <br>
+  <sub><i>Hover the pet to peek at name · level · XP bar · upcoming stage</i></sub>
+</div>
+
+- 🔒 **Zero-risk, fully local.** No cloud, no telemetry, no account, no data ever leaves your machine. Open source, MIT-licensed, fully auditable.
+- 🪶 **Zero-setup.** No hook configuration. petpet auto-discovers existing session logs on launch.
+- 🤖 **Multi-agent.** One pet eats events from every supported AI coding tool; XP accumulates in a single pool.
+- 🗂️ **Multi-pet.** Raise a fleet — switch the active companion any time; the rest hold their state.
+
+<br>
+
+###  🦄 Three Built-in Difficulty Templates
+
+<div align="center">
+
+<img src="assets/screenshots/three-eggs.png" alt="Three difficulty eggs" width="720">
+
+| | Template | Difficulty | Default name | Hatch (Opus 4.7) | L99 (heavy use) |
+|:---:|:---:|:---:|:---:|:---:|:---:|
+| <img src="templates/builtin/unicorn/thumb.png" width="72"> | **Unicorn** | 🟢 Easy | Sparkle | ~5–10 conv | ~30 days |
+| <img src="templates/builtin/sun/thumb.png" width="72"> | **Sun (Wukong)** | 🟡 Medium | Wukong | ~15–20 conv | ~60 days |
+| <img src="templates/builtin/kingkong/thumb.png" width="72"> | **KingKong** | 🔴 Hard | KingKong | ~30+ conv | ~150 days |
+
+</div>
+
+**Hard mode philosophy** — KingKong won't budge for idle chat. Only deliberate work counts: AI token usage, completed tasks, dispatched subagents. Want a titan? Earn it.
+
+<br>
+
+###  🔮 The Evolution Engine
+
+Every pet has **10 evolution stages** — egg → newborn → six juvenile / adult forms → final apex form. XP accrues from real-world events; level thresholds gate visual transformations.
+
+<div align="center">
+  <img src="assets/screenshots/evolution-strip-all.png" alt="Evolution stages across the three templates" width="780">
+</div>
+
+**The XP pipeline**
+
+```
+   Token usage   ┐
+   Activity     ─┼──→  Algorithm   ──→  Rule multiplier  ──→  XP
+   Manual grants┘     (invariant)       (per-template)
+```
+
+**Algorithm core** (`src/xp/algorithm.rs`, version-pinned, cross-install identical):
+
+```text
+weighted = input·1 + output·5 + reasoning·5 + cache_create·1.25 + cache_read·0.1
+raw      = weighted / 60,000 × tier_mult × confidence × growth_curve(level)
+xp       = round(raw).clamp(0, tier_cap)
+```
+
+**Tier multipliers** — capability bands stay stable across vendor price changes:
+
+| Tier | Examples | Mult | Per-event cap |
+|---|---|:---:|:---:|
+| 🌌 Frontier | Opus 4.7, GPT-5, o1+ | 1.5× | 10 XP |
+| 🌙 Mid | Sonnet, GPT-4o, Gemini 2.5 | 1.0× | 6 XP |
+| 🐰 Mini | Haiku, GPT-4o-mini, nano | 0.7× | 3 XP |
+
+**Growth curve** — `1 / (1 + 0.02 · level)`. High levels naturally diminish: at L25 you earn 67% per event, at L50 only 50%. No way to whale-rush to L99 in a weekend.
+
+**Per-template personality** — rule multipliers `[0.5, 2.0]` let each template flavor its preferences. Unicorn rewards every chat (chat-friendly), Sun halves it (medium pacing), KingKong zeros it out (token-only diet).
+
+<br>
+
+###  🐕‍🦺 Multi-Pet & Custom Templates
+
+**Switch any time.** The active pet absorbs live events; the rest preserve their state forever. Run a parallel breeding program if you like.
+
+**Roll your own pet.** The built-in **Template Creator** gets you from blank to playable in under 3 minutes:
+
+1. Pick a **levels preset** — `short` / `medium` / `long` XP curve
+2. Pick a **stages preset** — `simple` (5 stages) / `balanced` (7) / `extended` (10)
+3. Fill in:
+   - Name, description, flavor text
+   - 10 sprite PNGs (drag-and-drop)
+   - Per-rule XP weights and per-model boosts
+   - Theme color + label chips
+
+Templates live at `~/.petpet/templates/<id>/` — pure JSON + PNGs. Hand-edit, git-version, share with friends. No proprietary format anywhere.
+
+<br>
+
+###  📊 Dashboard
+
+Click your pet → opens the **Trainer Card**: a per-pet (or "All") usage dashboard tracking your spend, XP gains, model breakdown, and every recent move.
+
+<div align="center">
+  <img src="assets/screenshots/dashboard.png" alt="Trainer Card dashboard — All view: 3 pets, $8273.25 lifetime spend, 25K XP, 14B tokens, per-provider breakdown, recent moves" width="540">
+</div>
+
+- 💰 **Feeding Bill** — today / this week / this month / lifetime USD + token totals
+- 📈 **Per-provider breakdown** — Claude vs Codex vs OpenCode vs Aider, tokens + XP earned each
+- 📜 **Recent moves** — every XP gain logged with timestamp, pet, amount, and source (`usage` / `activity` / `manual`)
+- 🏆 **All vs single-pet toggle** — `All` aggregates every pet you've ever raised (including pre-install historical sessions, display-only)
+
+On launch, petpet performs **async historical import** of past session logs — your dashboard isn't empty on Day 1.
+
+<br>
+
+###  📦 Pet & Template Sharing
+
+Pack any pet (snapshot + XP history + custom name) or any template into a `.petpet` archive. Toss it on USB / Discord / GitHub releases. The recipient imports, schema is validated end-to-end:
+
+```
+✓ Manifest schema version       ✓ Sprite completeness (10 × PNG)
+✓ XP curve monotonicity         ✓ Rule shape (no unknown source_type)
+✓ SHA-256 checksums             ✓ No path traversal in archive
+```
+
+Invalid archives are **rejected**, never silently importing broken state.
+
+<br>
+
