The Plotly tutorial gets a section "9 · Web figures for a docs site".

• It saves a canvas as waves.plotly.json and shows the hints from canvas.to_json(alt=...).
• It explains how the palette and the text colour apply: traces without a colour, traces in a default colour, a black reference line, and named colours.
• It embeds the file with the theme's PlotlyFigure.
• It notes that a notebook's Plotly outputs are shown the same way on the docs site without saving.

The "Web figures" guide now points to starlight-theme 0.8 for the palette and hints, and to the tutorial.

The notebook runs locally from top to bottom, and the pre-commit hooks pass.
