iOS HEIC filename mismatch
Images uploaded from iOS Safari were failing silently. The photo library on iOS reports a .HEIC filename even when the browser has already transcoded the image to JPEG for the upload. The backend extension allowlist doesn't know about .heic, so it rejected the upload.
The fix is a _normalizeFilename() helper in PostService that inspects the XFile's mimeType property (set by the browser, not derived from the filename) and overwrites the extension if they disagree. image/jpeg with a .HEIC filename becomes .jpg. The MIME type is ground truth; the filename is not.
nginx upload 404s
Uploaded images were 404ing on the production server even though the files existed on disk. The nginx config had two location blocks that were in conflict:
location ~* \.(jpg|jpeg|png|gif|webp|...)$ { ... } # regex: matches /uploads/foo.jpg
location /uploads/ { proxy_pass http://go_backend; } # prefix: also matches
nginx's regex locations beat prefix locations by default — so image requests to /uploads/ were being matched by the asset-caching regex rule, which did try_files $uri =404 against the wrong root directory. The fix is location ^~ /uploads/ — the ^~ prefix modifier means "if this matches, stop evaluating regex rules."
Comment reply style
The reply nesting in comment threads was rendering the vertical connection line inside the row layout, which pushed content to the right. Moved the line to a Stack with a Positioned overlay so it sits at the left edge without affecting the horizontal layout of the reply content.
