/*
 * Blog styles for phppointofsale.com
 *
 * Loaded only on /blog and /blog/<slug>. Typography, colours and buttons reuse
 * the main site's palette so the blog reads as part of the website rather than
 * an embedded application.
 *
 * Layout rules that the migration depends on:
 *   - wide comparison tables scroll inside their own container, never the page
 *   - images are fluid and never overflow their column
 *   - the table of contents is a sticky sidebar on desktop and a collapsible
 *     block above the article on smaller screens
