release: v0.3.1

Adds a new debug panel button that injects any adventurers, quests,
bosses, equipment, upgrades, achievements, zones, and exploration areas
that exist in the current game data but are missing from an existing
player save (e.g. content added after the save was first created).

+## Art Assets
+
+Game art is generated via the Gemini API (`gemini-3-pro-image-preview`, ~$0.134/image at 1K resolution) and hosted on the CDN at `https://cdn.nhcarrigan.com/elysium/`.
+
+### Process
+1. Generate images with `curl` to `https://generativelanguage.googleapis.com/v1beta/models/gemini-3-pro-image-preview:generateContent?key=<API_KEY>`, requesting soft-shaded anime style
+2. Save responses to `/home/naomi/code/naomi/elysium/img/<category>/<id>.jpg`
+3. Upload to R2 with the AWS CLI — credentials are in the global `~/.claude/CLAUDE.md` (never commit them here)
+4. Delete the local `img/` directory before committing (images live on CDN only)
+
+### CDN URL Helper
+`apps/web/src/utils/cdn.ts` exports `cdnImage(folder, id)` → `https://cdn.nhcarrigan.com/elysium/<folder>/<id>.jpg`
+
+### Directory → Category Mapping
+| Game entity | CDN folder |
+|---|---|
+| Zones | `zones` |
+| Bosses | `bosses` |
+| Quests | `quests` |

+
+### API Rate Limits
+- 250 images/day per API key — use a second key if quota is hit
+- Free-tier keys cannot use `gemini-3-pro-image-preview`; key must be on a billing-linked project

 ## About Page
 
 The About page (`apps/web/src/components/game/aboutPanel.tsx`) contains a **How to Play** guide that should be kept up to date as new features are added to the game. When implementing new game systems, zones, mechanics, or significant UI features, update the `HOW_TO_PLAY` array in `aboutPanel.tsx` to include a description of the new feature.
