New homepage (#861)
* Paste button * Logo and animated blobs * Predictable initial blob position * Initial blob shape * Update canvas on resize if not updating every frame * lol * Get styles from CSS * Background blobs * Fade into the center * Get initial focus * Pause time while page is hidden * Footer * Optimise amount of initial CSS * More CSS optimisation * Install button * Home page with demo loading * Tweak size * Replace thumbnails * Responsive demo section * Responsive main section * Remove debug stuff * Fix prerender SVG size * Changes from feedback * Blob nudges (#872) * more smaller blobs * less blobs that are practically invisible * more dynamic speed range and stronger gravity * Reverting resize observer change The content rect is different to getBoundingClientRect Co-authored-by: Adam Argyle <atom@argyleink.com>
