Closes #13

• episodes/fig/open-definitions-venn.svg: new figure (OSI, OSHWA, UNESCO open science hardware, with the shared idea in the centre). Drawn as SVG with a title, long description and alt text in the page. I rendered it to check the layout.
• episodes/introduction.md: new section 'What counts as open?' with the figure, plus a 'Grey areas' challenge with four cases (museum 3D shell scans, code open but circuit files on request, non-commercial license, RISC-V from UC Berkeley) and discussion points.

The diagram is deliberately a simplification and says so. The OSI/OSHWA/UNESCO wording is from the lesson's own text and Lesson 3; I did not re-read the full OSI or OSHWA definitions, so please check the descriptions. Touches the same file as #38 in a different place.

If you have source files that require output and figures to be generated (e.g. R Markdown), then it is important to make sure the generated figures and output are reproducible.

This output provides a way for you to inspect the output in a diff-friendly manner so that it's easy to see the changes that occur due to new software versions or randomisation.
