"""note_attachments.filename (any-file attachments — M6 1900)

Revision ID: 0019
Revises: 0018
Create Date: 2026-07-23

Attachments broaden beyond images to any file; the original filename is recorded
for the download name + display of non-image files. Nullable (old image rows have
none — they render inline by mime anyway).
