/* MediaWiki:Common.js — grantha.io  (v7)
/* MediaWiki:Common.js */
*
* Changes vs v6:
*  1. BUG FIX: Main IIFE was never properly closed — About link block was
*    pasted inside it without the closing }() ); which broke the module
*    boundary and killed the by-Author toggle. Each block is now its
*    own self-contained IIFE.
*  2. TOC: "Beginning" link removed.
*  3. TOC: Heading label → "विषयसूची".
*  4. TOC: मूल / उल्लेख nav links injected at top of TOC panel.
*  5. TOC: All subsections expanded by default.
*  6. TOC: Only the active item is bold; all others are normal weight.
*  7. About link URL derived from wgArticlePath — works under any
*    sub-path install (e.g. /My_wiki/). Points to "My_wiki:About".
*  8. TOC customisations skipped on Main_Page and About pages.
*  9. Uses Vector's native TOC with IntersectionObserver-based active highlight.

   Devanagari page titles, site-wide  (window.grTitles)
   ───────────────────────────────────────────────────────────────
   One source of truth for "what is this page called": the Main Page
   catalogue, where every published work and commentary is listed as
   [[Slug|देवनागरी नाम]]. update_main_page.py keeps that list current,
   so a newly pushed commentary gets its Devanagari name everywhere
   without anyone editing a hard-coded list.

   Used by:
     • readerToolbar.js search results (grDocDisplayTitle & co. ask
       grTitles first, then fall back to their own GR_DOC_TITLES map)
     • the Updates page
     • this block itself, which relabels any link on the page whose
       text is still the English slug (e.g. the "Vadavali · Bhavavivaranam"
       page-nav line), the mobile page heading, and the browser tab title.

   The catalogue is cached in localStorage for CACHE_HOURS and refreshed
   in the background, so lookups are synchronous on almost every view.

   Mobile (Minerva): the same two items in the menu panel, after "Home".
   "Updates" opens the page My_wiki:Updates, which has two parts:

   1. What's new — filled in automatically from the wiki's edit history
      into <div id="gr-updates-feed">. Nothing to maintain by hand:
        • New      a page created in the last WINDOW_DAYS days
        • Updated  an existing page whose edits in that window add up to
                   at least UPDATE_MIN_BYTES (so typo fixes don't show)
      Titles are the Devanagari names from window.grTitles (Main Page catalogue).
      Test pages, helper subpages (/Ullekha, /Moola, /C1 …) and deleted
      pages are left out.
   2. Announcements & events — a card editors fill by hand with
      {{Bulletin|type=…|date=…|title=…|text=…}} lines on that page.

   Styling: MediaWiki:Common.css §37 (no inline styles here).

/* ── HASH REVEAL ───────────────────────────────────────────────────────
   A copied id or a bookmark citation is only useful if its #link actually
   lands on the block. The browser's own fragment scroll fires once, at
   parse time, and then our fonts swap in and the teeka blocks inject -
   the page grows under the reader and the target drifts off screen. It
   looks exactly like the link didn't work.

   This retries until the element exists and re-settles after late content
   arrives. It used to live in copyId.js (Editor extension), which is no
   longer loaded on this wiki, so it moves here where it always runs. If
   copyId IS loaded it does the same job; both are idempotent, and the
   guard below keeps them from fighting over the same jump. */
