/* OPTIONAL. Append to MediaWiki:Common.js only if you want inline highlight-and-annotate
   on long-form pages (white paper, book chapters). Loads the Hypothesis client on pages
   tagged with the "Annotate" category. Readers need a free Hypothesis account to annotate;
   anyone can read annotations. Remove this block to turn it off. */

/* ---- Pin the sidebar (Main menu) open by default for every visitor -----------------
   Vector 2022 only shows Main menu as a permanent left column once a user pins it
   (client preference, saved per-account/browser). This triggers that same built-in
   pin action automatically on every page load, so it defaults to open for everyone
   instead of only whoever has pinned it themselves. Skipped on narrow/mobile
   viewports, where a permanently-open sidebar would crowd out the page content. */

    /* Re-check and re-click every tick rather than stopping at first success: the
       button exists in the DOM from initial render but Vector wires up its click
       handler, and re-applies its own pin/unpin state from the (empty, for a fresh
       visitor) saved preference, slightly later -- an early click can silently no-op
       or get overwritten right after. Re-asserting for a few seconds outlasts that. */
