Edit in the browser

While astro dev is running, press e on any slide:

• its source file opens in a panel next to it
• type — it’s saved as you go and the slide updates live: only what changed is swapped in, no reload or flicker
• your step, the camera and a running recording stay; speaker notes and the presenter window follow
• add, remove or rename slide files — every window keeps its place
• the panel follows you from slide to slide; Esc closes it

Try it with bun run dev — the editor is never part of a production build.
