# SectionHead

The title row at three levels: the page h1 (Nunito 800 32px), a pane title (20px) and a section label (tracked uppercase, muted). Optionally one line beneath and one action at the far edge.

```html
<div class="postie-sh postie-sh--page"><div class="postie-sh__text"><h1 class="postie-sh__title">Accounts</h1><p class="postie-sh__sub">Four connected.</p></div><div class="postie-sh__slot">…Button…</div></div>
<div class="postie-sh postie-sh--section"><div class="postie-sh__text"><h2 class="postie-sh__title">Agent activity · today</h2></div><a class="postie-sh__action" href="#">Full log</a></div>
```

**When.** One `page` head per screen. `pane` for each column of the three-pane inbox. `section` for groups inside a pane or dashboard column. The sub line is for a status sentence, not a description ("Four connected. All syncing.").

**Never.**
- Never a rule under the title; the space and the type weight do the separating (tonal-step).
- Never a display title in the accent, and never a title over 32px inside the app (that scale is the marketing hero's).
- Never more than one action at section level — two links means the section needs splitting.
- Never a sentence with an exclamation mark or a welcome ("Welcome back, Frank!") — the voice is crisp and expert.
