# Idempotent Termux prereq installer for aistudio-api.
#
# What it does:
#   1. Ensures pkg: proot-distro, ca-certificates, curl.
#   2. Installs proot-distro container ${AISTUDIO_PROOT_NAME} (default
#      aistudio-api) — Ubuntu 24.04 from termux/proot-distro. Skips if
#      already present so it never collides with the user's own
#      `ubuntu` (or any other) container.
#   3. Inside the container, apt-installs the glibc runtime deps
#      CloakBrowser actually needs (libnss3, libnspr4, libgbm1,
#      libasound2, libxkbcommon0, libxcomposite1, libxdamage1,
#      libxrandr2, libxkbcommon0, libatk-bridge2.0-0, libatk1.0-0,
#      libatspi2.0-0, libgtk-3-0, libnotify4, fonts-liberation).
#   4. Downloads CloakBrowser into
#      <project_root>/.cloakbrowser/chromium-<ver>/. Skips if already
#      cached. Extracts in place; copies the chrome tree into the
#      container at /opt/cloakbrowser/ so the wrapper can --bind it.
#
# Flags:
#   --project-root PATH      where to place .cloakbrowser (default: cwd)
#   --proot-name NAME        container name (default: aistudio-api)
#   --proot-distro IMAGE     OCI image to install (default: ubuntu:24.04)
#   --chromium-version VER   CloakBrowser chromium version
#                            (default: 146.0.7680.177.3)
#   --skip-proot-install     don't create/update proot container
#   --skip-browser-download  don't re-fetch CloakBrowser tarball
#
# Re-running is safe and fast: each step short-circuits when its
# precondition is already satisfied.
