REM when the console codepage matches the file encoding, and forcing it with
REM "chcp 65001" makes cmd mis-read this UTF-8 .bat on a double-click launch
REM (the window then fails to start). ASCII renders the same in every codepage.

REM Python there - so one start ran on PlatformIO's Python and the next on
REM Python 3.12 (2026-09-25 / 09-27): two installs, each raised only when it
REM happened to run, and both shared with other tools whose own pins the
REM raises broke. Order: a venv in this folder, else the Python launcher's
REM 3.12 (the version the lock is compiled for), else PATH. The window and

REM --reload-dir src: only watch the source tree. By default --reload watches
REM the whole project, including data/ where the app constantly writes the
REM metadata cache + SQLite DBs - that spammed "watchfiles: N changes detected"
REM and risked reload churn. Scoping to src/ keeps hot-reload for code while the
REM data writes go unwatched. (The frontend is served statically - no app
REM reload needed for index.html edits; just refresh the browser.)
REM --timeout-graceful-shutdown: backstop so lingering connections (an SSE
REM stream from a tab that never got the shutdown signal, e.g. a sleeping
