Replaces the hand-written Tailwind subset in app.css with a real, purged Tailwind build: scripts/build_css.py runs the pinned, SHA-256-checked standalone Tailwind CLI (no Node), the generated tailwind.css and plugin-frame.css are committed, and CI fails when they are stale. The Pi never builds anything. The login page (#683) now links tailwind.css too, and the load-order test covers every template that links app.css.

"""The stdlib gzip fallback must compress the UI's text assets.
|
|
|
|
flask-compress is optional (app.py tolerates its absence). Without a fallback a
|
|
Pi missing it ships ~1.2 MB of uncompressed JavaScript to a phone over WiFi on
|
|
every first load and every update. These pin the fallback's contract: text
|
|
assets compress and round-trip byte-for-byte, clients that don't ask for gzip
|
|
get the original bytes, and small or non-text responses are left alone.
