// Shared helper for the admin "Server Settings" Mods, which regenerate
// GameEngine/config.php from the constant_format.tpl template.
//
// Issue #322: each Mod used to read the install-time copy
// GameEngine/Admin/Mods/constant_format.tpl. That copy is written once by the
// installer and is gitignored, so a code update NEVER refreshes it. When a new
// line is added to config.php (e.g. the per-user LANG block, issue #166),
// servers installed before that change keep the stale copy and the admin panel
// silently rewrites config.php without the new line.
//
// Fix: prefer the version-controlled template (install/data/constant_format.tpl)
// so shipping a new template via git is enough. Fall back to the install-time
// copy only when the install folder was deleted (a common hardening step once
// setup is done).

    // Placeholders are left untouched for the caller to fill in, with ONE
    // exception: %CRONKEY%. Every edit*.php mod regenerates config.php from this
    // template and replaces only the placeholders it knows about, so a value that
    // no mod handles would be written to config.php literally — breaking the key
    // used to call cron.php over HTTP. CRON_KEY is not something the admin edits
    // in any of those forms, so it is resolved here, once, for all callers:
    //   - existing server  -> keep the current CRON_KEY (survives config saves)
    //   - key not defined  -> provision a fresh random one (servers installed
    //                         before CRON_KEY existed in the template)
    // $overrides permite unui mod de editare sa IMPUNA o valoare pentru un
    // placeholder pe care altfel l-am pastra din constanta curenta (ex.
    // editServerSet care schimba HERO_BASE_REGEN). Celelalte module apeleaza
    // fara argumente si valorile curente raman neatinse.
