// 
// Build-4229938 computer (电脑) catalog: the computers themselves plus the files and emails that
// can be unlocked on them. Read from the configured client-data directory; none of the three
// source tables ship in the v0.3 Configs folder. Regenerate with _gen_computer_cfg.py.
// The client treats presence as the unlock flag, so every row here simply becomes unlocked:
// ComputerIndexerPanelStore.lua:150/272 iterate the computer's own FileList and look each id up
// in InfoMinor.ComputerUnlockInfo.UnlockFiles — an absent row is what hides the file.
// ComputerUtils.lua:9/84 do the same presence check for files and emails.
// ComputerUtils.lua:19/94 read ComputerInfos[computerId] before letting a computer open.
// Rows are stamped IsRead = false on purpose: ComputerUtils.lua:122 reports that flag as the
// unread badge, and unlocking everything already-read would remove the reason to open them.
// Rows the game retired with IsDelete are already excluded by the generator.
