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.
