/*****************************************************
DOCS

Styles used only by pages under /docs/ — table column widths, the template
chooser, and the interactive colour lab.

This is documentation furniture, not framework. A site built with Xanthan never
loads it unless it keeps the docs.

Loads:    only on pages whose URL contains /docs/ (see html/html-head.html)
Used by:  docs/getting-started/templates.md, docs/reference/colors-and-fonts.md
Needs:    base.css tokens
Not here: anything a reader's own site would use
*****************************************************/

/*
  Reference table layout: pins column widths for the
  standard three-column pattern (Field | Example | What it does).
  Assumes most docs tables follow this pattern.
  If a table on a docs page has a different structure,
  add class="auto-table" and override table-layout: auto on it.
