# Regenerates hyprlua's audio-panel from hyprdrive's supersonic-booster — the
# same PipeWire mixer panel (Applications / Output Devices / Input Devices /
# General Settings tabs), plain-themed instead of hologram-styled.
#
# Run BY HAND whenever hyprdrive's supersonic-booster changes and you want
# those changes reflected here. Never wired into sysupdate.sh. Modeled
# directly on regen-beacon.sh — see that script for the full rationale; the
# short version:
#
#   1. rm -rf + cp -r the hyprdrive source tree in fresh (not an incremental
#      patch), dropping style/ and any __pycache__.
#   2. Copies in the hand-maintained plain stylesheet from
#      desktopenvs/hyprlua/audio-panel-theme/ (never written to by this
#      script — edit that by hand for a different plain look).
#   3. Flips the copied config.py's hologram default to False (the real
#      hyprdrive supersonic-booster defaults to True and is never touched by
#      this script).
#   4. Runs one ordered rename table over every file's content AND over
#      filenames: supersonic-booster -> audio-panel, plus the CamelCase
#      class-name and UI-label variants actually present in the source
#      (checked empirically, not guessed — see the grep in the commit that
#      introduced this script). Also rewrites the literal "hyprdrive" ->
#      "hyprlua" (docstrings, and critically anything that still points at
#      desktopenvs/hyprdrive/scripts/ after the rename).
#
# The rename table intentionally does NOT touch the `.sb-*` CSS class names
# supersonic-booster/audio-panel use — that prefix doesn't contain
# "supersonic-booster"/"supersonicbooster" as a substring, so the audio-panel
# plain stylesheet targets them unchanged.
