rem  Guanlan start.bat
rem
rem  ASCII ONLY ON PURPOSE. Chinese text inside a .bat is codepage-dependent
rem  (console cp936 / cp65001 / system locale), and cmd.exe has been seen to
rem  mis-parse such lines and then try to EXECUTE parts of them
rem  ("'...' is not recognized as an internal or external command").
rem  So every .bat in this package is pure ASCII; all Chinese guidance lives in
rem  README (see "README" text file at the install root) and docs\.
rem  The rule is enforced by src\entry_refs.py (check.bat reports it) and by the
rem  packer: a .bat with non-ASCII bytes never ships.
rem
rem  Default (double-click) : no-window start via pythonw.exe + the launcher.
rem      A .bat is itself a console program, so Windows opens a window for a
rem      moment; this script exits at once and the window closes by itself.
rem      A .bat cannot avoid that flash. For a truly windowless start use the
rem      shortcut created by install.bat / install.ps1:
rem          [install dir]\start_guanlan.lnk     (ASCII name: console / CI / scripts)
rem          [install dir] and Desktop: a .lnk with the Chinese product name
rem      Both point straight at .venv\Scripts\pythonw.exe, so neither cmd.exe nor
rem      Windows Script Host is involved.
rem
rem  start.bat console      : foreground mode (old behaviour). Keeps this window
rem                           open and prints live logs; closing it stops serve.
rem  start.bat help         : this text.
rem
rem  Logs (docs section 11.2): logs\serve.log and logs\start_hidden.log.
