Excalidraw fork automates blog diagram exports

This is the kind of niche automation AI coding is actually good at: spotting a repetitive annoyance and turning it into a tiny local tool. The big idea here is not Excalidraw itself, it’s collapsing export friction into a naming convention.

• –The first GitHub Action proved the concept, but it pushed the feedback loop into CI and broke down on ARM Macs.
• –Local auto-export keeps blog assets co-located with the `.excalidraw` source, so preview stays honest while you write.
• –`export_` as a frame prefix is a clean little API: intent lives in the filename, not in a separate settings panel.
• –Separate light and dark SVGs solve a real publishing problem for theme-aware blogs without extra manual steps.
• –Release artifacts make the fork easy to try, which matters when the whole point is reducing one person's publishing friction.
