 **Emoji shortcodes are the full GitHub/Discord `:name:` set** (~4869 names), generated once from the `emoji` library by `rendering.py` `build_emoji_shortcodes()`; the frontend gets the identical map via the generated `static/js/emoji-shortcodes.js` (regenerate with `devplace emoji-sync` after bumping the dependency, never hand-edit).
 
-**Template em-dash normalization:** the shared `templates.env.template_class` runs every rendered template's final HTML through `normalize_em_dash` - the em-dash character and its HTML entity forms all become a plain hyphen, application-wide. One hook; never re-strip em-dash per template.
+**Em-dash normalization:** `_normalize_dashes` in `rendering.py` replaces all forms (em dash `\u2014`, en dash `\u2013`, and their HTML entities) with a hyphen BEFORE mistune processes the text. Runs inside `_render_content`/`_render_title` which are `@lru_cache`d, so each unique text is normalized once. No per-template overhead.
