Purpose
A four-category in-game help window for private-server players, maintained by the administrator through locale text files. It provides account-safety guidance, community addresses, reporting instructions and team contacts without embedding a browser or requesting account credentials.

M2City r1 corrections
The original opened new event text blocks on category changes without clearing the old ones, could divide by zero at exactly 18 lines, and used undefined lowercase none during destruction. The reviewed panel owns one event block at a time, uses a None sentinel instead of risking another window's event index zero, clamps scroll to the available lines and automatically hides the scrollbar for short pages. Open/Close reuse the window; Destroy is idempotent. The description child follows the owning window and does not intercept clicks. Category indices and failed text registration are handled explicitly.
English example labels and four concise editable pages replace old server-specific addresses and repeated filler in the reviewed overlay. These are examples to localize, not live support details for your server. The original archive is preserved for comparison and notices.

Installation
Pack reviewed/root/uiguifaq.py and reviewed/uiscript/guifaq.py. Copy locale/LOCALE/faq into your actual locale directory and define CARDS_DESC_1 through CARDS_DESC_4 in uiScriptLocale using that locale's root. Keep the text encoding consistent with your client. Merge the supplied event.SetVisibleLineCount native wrapper only when missing, preserving the existing method table; the underlying event manager method must exist.
Create a FaqButton or another explicit entry point. Initialize the owner window's self.faq to None, construct GuiFaq once, and call Open(), not only Show(). Destroy and clear it during owner destruction/logout. Recreate it when changing locale. The detailed INTEGRATION.txt supersedes the old document.h example that created a new window on every click. No server or quest change is required.

Validation
All nine supplied text/source files were read. Fake UI/event tests covered empty, 17/18/19/200-line pages, scroll extremes, all categories, invalid selection, failed registration, 100 reopen/close cycles and repeated destruction. They verified an unrelated event index zero remains untouched. Actual client layout, event rendering, locale wrapping and in-game navigation remain untested. Original author/version could not be independently established; none was invented. Redistribution was confirmed by the supplying owner.
