Guess the wind

This is a practice note, to try writing in MDX. Everything above the line is frontmatter; everything below is Markdown, plus components.

Read the flag

The flag lifts and flutters with the wind. Move the slider to your call, then check it.

Your call:

10 mph

How this works

• Text is plain Markdown: headings, lists, bold, links.
• The interactive part is a Preact component in components/, placed with one line and client:visible, so its code only loads when it scrolls into view.
• The wind here is random. A later version could replay real wind readings from a match (Linear 180-3469).
