- Dockerfile: 去掉 COPY . .，镜像退化为纯依赖层，改代码不再需要重建镜像 - Dockerfile: 补 libgl1 / libxcb1 / libglib2.0-0 等 X11 库。opencv-python 在导入时需要它们，而 tools/utils.py 会经 slider_util 导入 cv2 —— 缺了不是某个边角功能挂掉，是整个应用起不来（已在真机冒烟中验证） - Dockerfile: 补 tzdata，否则 TZ=Asia/Shanghai 被静默忽略，所有时间戳落成 UTC - Dockerfile: apt 与 pip 均改走国内源。deb.debian.org 实测约 13 kB/s，96 MB 构建依赖要跑半小时以上 - docker-compose: 挂载 ./ 到 /app，部署流程从「重建镜像」变成「重传 + 重启」 - main.py: 启动时若缺 api/webui/index.html 就打印警告，避免只返回一段 JSON 却看着一切正常

# No browser is bundled on purpose. On this deployment the crawler attaches over
|
|
# CDP to the Chrome already running on the host (see the 接管已有 Chrome setting),
|
|
# so shipping a second copy of Chromium would only add hundreds of megabytes and
|
|
# a login state that nothing uses. The Playwright Python package is still needed
|
|
# -- that is what speaks CDP -- hence PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD.

# asyncmy compiles a Cython extension, so a toolchain has to exist at build time.

# deb.debian.org is effectively unusable from this network -- it was pulling the

# 96 MB of build dependencies at roughly 13 kB/s, which puts a build at well over

# half an hour. Point apt at a domestic mirror; override APT_MIRROR when building

|

# them the *application* fails to import, not just some image utility. tzdata is
|
|
# here because TZ=Asia/Shanghai is silently ignored without it, which would put
|
|
# every stored timestamp in UTC.

# The pip mirror is set for the same reason as the apt one: this host's route to
|

# the public index is slow.
