Devlog #21: Markdown editor for descriptions

The description editor in Quedula supports Markdown. This was a conscious decision and it turned out to be the right one.

Basic Markdown — bold, italic, lists, links — is what you actually need in a video description. We don't need tables or H1-H6 headings.

We intentionally limited the supported Markdown subset. This simplifies conversion to plain text for platforms that don't support markup, and removes the temptation to write "too complex" for a video description.

Preview works in real time — editor column on the left, rendered result on the right. Mobile view: two tabs.

One unexpected insight: users actively use bullet lists for hashtags.
