What the model said

I cleaned up `0.html`, fixing three bugs and some accessibility issues. None of it has been run in a browser: the check I tried to launch was blocked by this session's permissions.

## Bugs fixed
- **Help button hover hid the "?"**: the hover style set the background to `currentColor` while also changing `color`, so the text and background became the same colour. It now uses explicit colours.
- **Help button inherited the circle's styles**: the bare `button` selector gave the "?" button a 48px minimum size and the circle's 12px focus-ring offset. The circle styles are now scoped to a `.circle` class, and the help button has its own focus ring and a 24px target.
- **Touch hint said "Tap to cycle • Double-click reset"**: it now reads "Double-tap to reset" on touch devices and "Double-click to reset" elsewhere.

## Accessibility
- **Colour was announced twice**: the script rewrote the button's `aria-label` on every change, on top of the status live region. It also included a hex code that was wrong in dark mode. The label is now fixed and the status region does the announcing.
- **Help button "?" leaked into the circle's description**: the `hint` id now sits on a span wrapping only the hint text.
- **Help button labelling**: it now has a proper `aria-label` and `aria-controls`, and `aria-expanded` follows the actual visibility.
- **High contrast**: `prefers-contrast: more` now shows the circle at full opacity.
- **Text selection**: the circle has `user-select: none`, so Shift+click and double-click should no longer select the text below.

## Cleanup
- The duplicated change/persist/pulse logic in `changeColor` and the `dblclick` handler is merged into one `setIndex()` function.
- Removed dead code: the `colorHex` map, an unused `hint` variable, no-op `.hint` opacity rules, and redundant `aria-live`/`aria-atomic` on the status element.
- `transition: all` on the help button is replaced with specific properties.

## One visual change you may want reverted
I removed the `.color-indicator` dot. It was always the same colour as the circle it sat on, so it carried no information, and it didn't scale with the circle on hover. Say so if it was intentional and I'll put it back.

## Left alone
Double-click to reset conflicts with fast clicking: two quick clicks to advance two colours also trigger the reset to blue. I kept the behaviour because removing it is a product decision. My recommendation is to move reset to a key such as `Esc`, or to a small separate button.
