Markets: the price chart is AP3X/USD across every pool, not one pair

The chart card read one DexScreener pair (bAP3X/USDC on Aerodrome). It now
draws AP3X in USD aggregated over every pool with at least $1K of liquidity
- four on Base (Aerodrome USDC and WETH, Uniswap and QuickSwap cbBTC) and
Minswap's cAP3X/ADA on Cardano - from GeckoTerminal's per-pool USD candles:
price liquidity-weighted (a pool with no trade holds its last close), volume
summed. 15m / 1h / 4h / 1D, an OHLC + volume readout, and a footer naming the
pools. GeckoTerminal is keyless and rate-limited, so the pool list (6 h) and
candles (3 min) are kept in localStorage; when it is busy the card shows the
largest pool's DexScreener chart and retries. VyFi and LBank are not in its
feed and say so.

-## Note on the AI assistant
+## Fusion AI (powered by HAL 8)
 
-The chat widget in the bottom-right sends visitor messages to a
-third-party inference endpoint by default. `window.FUSION_AI_ENDPOINT`
-can be repointed at HAL 8's own OpenAI-compatible API
-(`https://hal8.odyssey-works.io/v1`) so conversations stay on
-Odyssey Works infrastructure.
+The red-eye button in the bottom-right is Fusion AI. The page holds no key.
+It posts to `https://hal8.odyssey-works.io/v1/public/fusion/chat`, and
+`window.FUSION_AI_ENDPOINT` overrides that for testing. The route runs
+HAL 8's headless pipeline under its own capped account: $1 a day for
+everyone, and per visitor 40 messages, 6 images and 1 video a day. Its full
+contract is `docs/FUSION.md` in the HAL 8 repository.
+
+- **Standard | Incognito** is the only control.
+  - Standard is `hal8-auto`; the conversation is kept in this browser only.
+  - Incognito is a Venice private model; nothing is kept, and generated
+    media is deleted after a day.
+- Chat, code, web search, images, video and voice are always on.
+- Python code blocks run in the visitor's browser.
+
+The launch film lives in `fusion/launch/`. It includes:
+
+- `fusion-ai-launch.mp4`, the 32-second, 16:9 cut shown on the HAL 8 page (the "Meet Fusion AI" card) and in the widget's "Watch the launch film" lightbox;
+- `poster.jpg`, its poster frame;
+- `fusion-ai-launch.vtt`, its subtitles.
+
+The film was rendered in Blender from the Apex Universe scene. The Fusion pane in it is the real widget, playing answers Fusion AI actually gave. The voice is ElevenLabs "Brian", and the score is original.
+
+The widget is `fusion/fusion.js` and `fusion/fusion.css`. After editing
+either, run `python3 tools/fusion_inject.py`: it inlines the CSS and
+re-stamps the module version inside `index.html`, and re-running it
+replaces rather than duplicates.
