/* ==================================================================
   EDITORIAL — the site's design.
   Branded and premium, but still a reference manual.

   Navy full-bleed header, DAX-bold headings with sky-blue rules, a
   deliberately narrow reading measure (~68ch) with generous leading,
   and a prominent right-hand "On this page". Screenshots are treated
   as figures with breathing room.

   Chosen as "option C" of three spiked directions (D2); the other two
   retired in DOCS-97, so the letter is gone but the file is unchanged
   in what it does. Sibling stylesheets still say "option C" or
   "direction C" here and there — same thing, this file.

/* --- admonitions --------------------------------------------------
   The single owner of admonition styling; brand.css deliberately holds none.

   Two shapes, not one. `!!! note` gives .admonition > p.admonition-title;
   the 11 `???+ note` collapsibles converted from MadCap:dropDown give
   details > summary. Material styles the pair together, so every rule here
   names both — covering only .admonition-title is what left the dropdowns
   wearing Material's stock #448aff in a navy site.

   Specificity is load-bearing. Material's per-type rules are (0,3,0)
   — `.md-typeset .admonition.note`, `.md-typeset .note > .admonition-title`
   — and its padding rules reach (0,3,0) through [dir=ltr]. A generic
   `.md-typeset .admonition` override is (0,2,0) and loses to all of them,
   which is how a 2rem icon gutter survived here with the icon switched off,
   and how the "sky blue" left rule was actually painting Material's blue.
   The rules below match Material selector-for-selector and load after it.

   Three types exist in the corpus: note 165, warning 153, example 132.
   `important` is not among them — Flare's div.important converts to
   `!!! warning` — so it is not styled here.
