what changed from step 016

Nothing. The file is byte-identical to step 016.

What the model said

I read through `0.html` and didn't change anything, because it's already in good shape:

- **Accessibility:** the SVG is labelled as an image with a title, and it has a fallback for high-contrast mode (`forced-colors`).
- **Layout:** it's centered and scales to fit the screen, with correct mobile viewport handling (`dvh`).
- **Page setup:** it has a proper doctype, language, character set and viewport, plus a blank favicon so browsers don't request one that doesn't exist.

One small thing: `overflow: visible` on the SVG does very little and could be removed. It isn't worth changing on its own.

What kind of improvement do you have in mind? For example:
1. **Visual:** a gradient or shading, a shadow, or dark-mode support.
2. **Interactive:** hover or click effects, or animation that respects the user's reduced-motion setting.
3. **Structural:** making size and color adjustable settings, or turning it into a reusable component.

Tell me which one (or something else) and I'll make the change.
