, well before the real search-insights.js
*
so the download
* begins as early as before. Repeat calls share the same downloads, a
* failed load is retried on the next call, and the versions / SRI
* hashes live only here.
*
* Algolia Insights is unaffected: window.aa above is still created in
* on every page and queues events until search-insights loads.
*
* window.loadAlgoliaLibs({ priority: 'high' }) (Oct 2026): used by the
* /search page, where the first results wait on these libraries. Chrome
* gives async scripts low priority, behind images and fonts; this asks
* for high instead (fetchpriority). Only the first call for a library
* sets its priority - later calls share that download.

/* 19 Oct 2026 - chat widget layout shift (field CLS).
Phones fail Core Web Vitals on CLS (p75 ~0.2 site-wide in CrUX for
months). Biggest cause found: HubSpot's chat container is fixed to
the bottom-right corner and changes size - 100x96 launcher to
282x253 when the welcome message pops up (~5 s after load), and
to full screen when a visitor opens the chat. Its top-left corner
moves, so Chrome scores it as a layout shift: 0.088 per page view
at 360x640 (0.044 at 412x850), on every page. Taps happen inside
the chat iframe, so the parent page never sees the input and the
open/close shifts count too.
Fix: whenever the container's size changes it is made transparent
for 400 ms (Chrome doesn't score shifts of invisible elements),
then shown again at its new size. Tested on live io1001 at 360x640
in a cookie-less frame: the 0.088 shift no longer appears. The chat
itself is unchanged - it just appears 0.4 s later at each resize.
Relies on HubSpot's container id; if that changes this does
nothing (no error). */
