+   CONTENT LINKS
+
+   myst-to-react colours content anchors through two classes: `.link` (plain
+   links) and `.hover-link` (cross-references, citations, footnotes). Upstream
+   defines both in `@myst-theme/styles` as blue-700/blue-400 with blue
+   decoration colours; the Sphinx builds render links in QuantEcon blue
+   instead. These rules re-colour the classes to the measured Sphinx values --
+   colour only. The underline itself (always-on, dotted for `.hover-link`) is
+   left as upstream ships it.
+
+   Specificity is matched to the upstream rules this overrides, with source
+   order breaking each tie (this file is @import-ed after `@myst-theme/styles`,
+   see styles/app.css):
+
+     - `.link` here (0,1,0) ties upstream `.link` -- wins on order.
+     - `.link:hover` (0,2,0) ties upstream's compiled `hover:` utility.
+     - `.dark :is(...)` (0,2,0) ties upstream's `dark:` -> `.link:is(.dark *)`.
+     - `.dark :is(...):hover` (0,3,0) ties `.link:hover:is(.dark *)`.
+
+   `text-decoration-color: currentColor` replaces upstream's separate blue
+   decoration utilities in one declaration per rule -- the underline always
+   draws in the link's own colour, as the Sphinx build's plain underline does.
