Refs #303. file.save / file.save_as can store a warm native geometry cache (cache: true, off by default) keyed to the document hash, app version and adapter revision. Opening shows a bounded preview from it until the rebuilt session replaces it. Any cache failure counts as a miss.
* docs: add OpenGraph and Twitter card tags to the book and web app
Links to the docs site and the browser app now unfurl with a preview card.
The book gets the tags through theme/head.hbs (og:title follows the page
title); the web app's index.html carries its own, pointing at /app/. Both
use the social preview image, now served from the book at /solidcraft/og.png.
