/* MediaWiki:Common.js — grantha.io (v7)
*
* Changes vs v6:
* 1. BUG FIX: The main IIFE was never properly closed in v6 — the "About"
* link injection block was pasted inside it without the closing }() );
* This broke the JS module boundary and caused the by-Author toggle on
* the main page to fail (the grHomeView IIFE ran in a corrupted scope).
* Fix: About link injection is now its own self-contained IIFE, cleanly
* separated from the transliteration/TOC IIFE.
* 2. TOC: Remove the auto-generated "Beginning" link (Vector 2022 always
* inserts a first TOC entry that links to the page top; on Sanskrit
* content pages this is unnecessary and clutters the TOC).
* 3. TOC: Add "मूल" (Moola) and "उल्लेख" (Ullekha) nav links below the
* document title area — Moola links back to the primary bhashya page
* (on teeka/vyakhya pages), Ullekha links to the references index page
* for the document. Both use the existing data-primary / doc-slug
* attributes already present in the page HTML.
* 4. All other behaviour identical to v6.
