+#### Page layout
+
+Every page — article, editor, file listing, search results, error — is laid out
+by the same three class names, which an application overriding one of the page
+templates has to keep:
+
+| Class | Role |
+|-------|------|
+| `wiki-page` | the grid: one column on a narrow screen, article plus outline from 768px up |
+| `wiki-toc` | the table of contents, first in the source, placed on the right on a wide screen |
+| `wiki-content` | the main column: article, editor form or listing, with its header |
+
+The TOC precedes the article in the source so a narrow screen shows it
+first, and the grid moves it to the right-hand column on a wide one. It is
+pinned with `position: sticky` and scrolls on its own once it outgrows the
+viewport. A page without headings renders no `wiki-toc` at all, and the grid
+falls back to a single centered column.
+
+#### Feedback
+
+Feedback shares one channel: the messages flashed by the server and the ones the
+browser raises on its own are all toasts, stacked in a `wiki-toasts` container
+fixed to the top right. Their markup comes from the `toast` macro of
+`WIKI_TOAST_TEMPLATE`, and the toasts the wiki raises by itself live in
+`wiki/toasts.html`.
+
+An application overriding `WIKI_BASE_TEMPLATE` renders its own stack. It
+includes `wiki/toasts.html` in it, so it never has to know the ids `wiki.js`
+reveals nor repeat their messages, and it renders the flashed messages itself if
+nothing else in the application already does:
+
+```jinja
+{% raw %}<div class="wiki-toasts">
+  {% for category, message in get_flashed_messages(with_categories=True) %}
+  {{ toast(message, category, autoshow=True) }}
+  {% endfor %}
+  {%- include "wiki/toasts.html" %}
+</div>{% endraw %}
+```
+
+To render those toasts as the rest of the application does, point
+`WIKI_TOAST_TEMPLATE` at a template of its own supplying a macro with the same
+signature — `toast(message, category='message', id=None, autoshow=False)`, where
+`id` marks a toast kept hidden until a script reveals it, and `autoshow` one
+`wiki.js` reveals as soon as the page is ready:
+
+```python
+app.config["WIKI_TOAST_TEMPLATE"] = "myapp/macros/toast.html"
+```
+
 #### Icons
 
 Templates never name a glyph directly. They ask for an *intent* — `search`,
