Is this file important? I feel, that you don’t review code after AI.

A PowerShell regex replacement misfired in my terminal and generated phantom files instead of modifying Globals.java. I've nuked the garbage files and force-updated the branch so it only contains the clean XSLT/Java fixes.

Issue Breakdown

The PCGen export engine was hardcoded to default to European A4 dimensions, completely ignoring the user's operating system locale settings.

An initial attempt to apply the US default using the frontend translation string "in_PaperLetter" caused the FreeMarkerExportHandler to crash with an Invalid export tag 'PAPERINFO.NAME' error, as the XML exporter requires the strict internal identifier.

Applied Fixes

Rewrote initPreferences() in Globals.java to evaluate Locale.getDefault().getCountry() dynamically, successfully assigning standard US Letter defaults for system environments set to US or CA.

Replaced the "in_PaperLetter" string with the correct "Letter" identifier across Globals.java and system\gameModes\default\paperInfo.lst to safely resolve the FreeMarker template crash.

Validated the fix locally; engine now auto-corrects corrupted preferences and correctly exports PDFs with 8.50 × 11.00 inch dimensions for American locales.
