/* Boot screen — visible while main.js is parsing/booting (or stuck on error).
   Hidden once `body.app-booted` is set by main.js after applyI18nToDom().
   If main.js never runs (parse error), this overlay stays put with whatever
   the inline console-capture script wrote into #bootLogs.
   Layout: the full boot stack is vertically centered, with a larger gap after
   the logo and tighter spacing between status, error, and logs. */
