Flesh out the in-app help drawers (images, worked examples, deeper coverage)

[ApocDev]

The ? help drawers (HelpButton in app/src/components/help-drawer.tsx) give a docs drawer on Coherence, Factory, What-if, TURD, Browse, the Block editor, and Tasks. The first pass is concise text, enough to orient. Later it should be more expansive:

• Images and diagrams, for example the canceling-mismatch visual on Coherence, a worked block-solver example on the Block editor, and the in-game capture flow on Tasks.
• Worked examples: a concrete "scale stone to 60/s" walkthrough, a real TURD pick and its effect, byproduct handling in hard mode.
• Deeper coverage: the full item-disposition model, edge cases, and the bridge sync model.

Decide first where the expansive docs live:

1. Cram more into the drawers, which is cramped for images and long-form.
2. A wiki or docs site for the long-form, image-rich version, with each drawer linking to its page. Drawers stay the concise contextual layer.
3. An in-app /docs route.

Leaning toward option 2: keep the drawers tight (contextual what and why) and host the deep, image-rich reference separately, with each drawer linking to its page.
