+## visual-style
+
+**Goal:** refresh the control panel's visual design — typography, colour tokens,
+spacing, and component styling — without changing operator workflows or panel
+behaviour.
+
+**Boundary:** presentation only (`panel.css`, templates, static assets); no new
+features. Styling must stay compatible with the panel CSP — rules live in
+`panel.css`, not inline (see [security.md](security.md) and the stylesheet
+header).
+
+**Done when:** the panel reflects an agreed visual direction (starting
+reference: [assets/selfpost-proof.html](assets/selfpost-proof.html)); light and
+dark schemes remain supported; readability and contrast are preserved.
+
+**Dependencies / risks:** CSP constraints on how styles are applied; visual
+regression across pages; low priority relative to functional work — take up
+after explicit agreement, independently of the feature roadmap order.
+**Version:** no bearing on semver.
