/*!
 * blog-blocks.css — styles for the 1CA blog editor's content blocks (v1, 2026-10-21).
 *
 * Canonical copy: onechanneladmin-latest/apps/web/src/components/RichTextEditor/blog-blocks.css
 * (the admin editor uses the same rules for its preview via blogBlocksCss.js). Copy this file
 * unchanged into any site that renders 1CA blog posts and load it AFTER the site's own blog CSS.
 *
 * Contract
 *  - Posts carry class names only (no <style>, no inline layout CSS). The save sanitizer keeps
 *    exactly the classes styled here (BLOG_BLOCK_CLASS_NAMES) plus the blog-faq__* FAQ classes.
 *  - Scope: put class "oca-content" on the element that wraps the post HTML. Blocks are styled
 *    inside .oca-content or inside an .oca-blog wrapper. Posts without block classes are untouched.
 *  - .oca-blog (optional wrapper inside the post) also applies the long-form "article theme":
 *    cream page, Instrument Sans body, Bricolage headings, section rhythm, table and FAQ styling.
 *  - Theme a site by overriding the --oca-* custom properties on .oca-content.
 *  - Fonts (load them in the page): Bricolage Grotesque 700/800, Instrument Sans 400-700,
 *    IBM Plex Mono 400/500, e.g. https://fonts.googleapis.com/css2?family=Bricolage+Grotesque:opsz,wght@12..96,700;12..96,800&family=Instrument+Sans:wght@400;500;600;700&family=IBM+Plex+Mono:wght@400;500&display=swap
 *
 * Blocks (HTML the editor writes):
 *  callout   <aside class="oca-callout oca-takeaways|oca-tip|oca-note|oca-warning">…</aside>
 *  answer    <p class="oca-answer">…</p>
 *  toc       <nav class="oca-toc [oca-toc--1col]"><p><strong>Title</strong></p><ol><li><a href="#id">…</a></li></ol></nav>
