+"""
+Slim the embedded cover art across the music library.
+
+WHY. iOS AVPlayer fetches the head of a streamed file in ~32 KB range requests, one round trip
+each, and it cannot reach audio until it has read past the whole ID3 tag. A 955 KB embedded JPEG
+(Ben Harper, 2026-08-29) therefore cost ~30 sequential round trips - a two-second silence on the
+iPhone that Android (ExoPlayer, one connection) never feels. 28% of the library rips carry art
+this size.
+
+THE LIMIT, AND WHY. Every track KEEPS an embedded front cover - the folder cover.jpg is this
+plugin's primary art, but embedded art is what any OTHER player/user of the files sees, so it
+stays. It is recompressed to fit the transport: 600x600 max (the iTunes standard, plenty for any
+lock screen), JPEG, quality stepped down from 85 until it fits in EMBED_TARGET = 80 KB. 80 KB
+plus the text frames keeps the whole tag within ~3 range-request chunks - imperceptible - while
+staying visually indistinguishable at the sizes any UI renders it.
+
+Only files whose picture frames total more than PROCESS_OVER = 100 KB are touched at all; a file
+already carrying reasonable art is left byte-identical.
+
+SAFETY. Work happens on a temp copy; the post-tag byte region (the audio, verbatim) is hashed
+before and after and must match or the original is kept. If an album folder has NO cover.jpg or
+folder.jpg, the original full-resolution embedded art is rescued to cover.jpg before compression.
+
+Usage:
+  slim-embedded-art.py                                 dry-run over ~/Music
+  slim-embedded-art.py "Albums/Ben Harper/[1994] ..."  dry-run, one directory
+  slim-embedded-art.py [subpath] --apply               actually rewrite
