+name: Fofos media
+description: Where the fofos website's media lives, and the one way to process it.
+version: 1
+---
+
+The fofos website's media sits under the **root location** in Fofos → Administration:
+
+- **`media/originals/`** — what people uploaded. Nothing regenerates these. Never convert one in place
+  and never delete one.
+- **`media/derived/`** — made from originals, for the public site. Safe to wipe and rebuild.
+
+**Process it through av-club, never a hand-written `ffmpeg` or `convert`.** av-club decodes HEIC, which
+every iPhone photo is and which sharp alone cannot read, and applies EXIF rotation.
+
+Read the **`media-conversion`** skill for how. If the owner is at a screen, the right-click tasks —
+Convert Image, Convert Video, Convert Audio, Extract Audio — are the better answer.
