/* ---- 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. */
