+## Coral Comments
+
+Post pages embed Coral with `customCSSURL: "/coral-transparent.css"`. Each
+site keeps its own copy at `sites/<name>/public/coral-transparent.css`.
+
+That CSS is the durable customization point for Coral UI changes: it is served
+by the blog site and loaded by Coral at runtime, so it survives Coral container
+rebuilds and image upgrades. It currently makes the embed background
+transparent, hides the redundant single "Comments" tab, and suppresses Coral's
+fixed-position floating notification bell so it cannot drift over article text.
