+Follow [gitmoji](https://gitmoji.dev) conventions. Use the **emoji character** (not the `:shortcode:`).
+
+## Format
+
+```
+<emoji> <imperative summary, third person>
+
+<longer explanation of what and why, wrap at 72 chars>
+
+<issue references, e.g. Closes #123, Fixes PROJ-456>
+```
+
+- Subject line under 72 characters.
+- Third-person imperative mood ("Adds feature", not "Add feature" or "Added feature").
+- Do not end the subject with a period.
+- Separate subject, body, and footer with blank lines.
+- Body and footer are **optional** — only include when the subject alone isn't self-explanatory or when issues need linking.
+- Body explains **what** changed and **why**.
+- Footer links related issues (GitHub `Closes #N` / Jira `PROJ-N`).
