From 852332e6dc82468fa56d8b89b39cae44e96480f7 Mon Sep 17 00:00:00 2001 From: Nico Hinderling Date: Tue, 3 Mar 2026 11:20:51 -0800 Subject: [PATCH 1/4] feat(snapshots): Add 40M pixel limit validation for snapshot images Validate image pixel counts before uploading to catch oversized images early, matching the backend's MAX_DIFF_PIXELS limit. Images exceeding 40,000,000 pixels are reported with their dimensions and the command fails before wasting bandwidth on uploads that would be rejected.
