/**
 * Summarize with AI - Public Styles
 *
 * Themes restyle links, buttons and content images heavily, so this file states
 * every property the layout depends on rather than trusting an inherited value.
 *
 * Three rules govern the whole file:
 *
 * 1. No `!important`. Everything here stays overridable by a theme, a child
 *    theme or the customiser.
 * 2. Specificity is kept to two or three classes: enough to win against the
 *    usual `.entry-content a` rules, low enough that a theme author overrides
 *    it with one more class.
 * 3. Anything worth changing is a custom property, so a theme can retheme the
 *    buttons without fighting selectors at all:
 *
 *      .share-with-ai { --swi-radius: 999px; --swi-gap: 6px; }
 *      .summarize-with-claude { --swi-bg: #b04c2f; --swi-bg-hover: #8f3d26; }
 *
 * Each service button also carries its own --swi-bg / --swi-bg-hover inline,
 * set by the renderer, so services registered through the
 * `summarizewithai_services` filter are styled without touching this file.
 *
 * @package SUMMARIZEAI
