The mobile copy/paste overlay's "🖼 Image" button (and drag-drop / paste)
now handles real-world photo batches:
- Up to 20 images per batch, uploaded with bounded concurrency (3) and a
live "Uploading N/M…" progress toast; a final summary reports successes,
any failures, and whether the 20-cap trimmed the selection (no silent
truncation).
- Per-file upload limit raised 10MB → 50MB (MAX_PASTE_IMAGE_BYTES in
buffer-limits.ts, env-overridable) so full-resolution phone photos and
large screenshots aren't rejected.
- Very large images are downscaled to <=4096px longest edge before upload:
fixes iOS Safari's ~16.7M-px <canvas> limit (which made huge photos fail
to re-encode and fall back to an original that tripped the magic-byte
check), and keeps batch uploads fast and small.
- Fix a latent concurrency bug the batch path exposed: the first parallel
uploads to a session raced on `mkdir(.claude-images)` and the EEXIST
losers 500'd. mkdir now treats an existing real directory as success
(re-verifying it isn't a planted symlink), so concurrent uploads succeed.
Verified end-to-end in a real browser (Playwright): downscale, >10MB
server acceptance, 20-cap, 20/20 concurrent uploads landing on disk.
