/* Designer library styles. Class names are prefixed so nothing collides with a
   host application's stylesheet in either direction.

   The block below is a plain :root definition, not a fallback. Nothing here
   checks whether the host already set these — equal specificity means the
   stylesheet loaded LAST wins. A host that wants its own palette must therefore
   redefine them in a stylesheet linked after designer.css, or with a stronger
   selector. Getting that backwards is silent: the wrong colours simply appear.

   These values are the Bluefin design system, so a host that shares that palette
   needs to do nothing.

   --wo-font-mono deliberately falls through to Consolas. Space Mono is only
   loaded by the standalone development host, which pulls it from Google Fonts.
   WorxOrder_Enterprise bans external font hosts — a locked-down customer network
   once left the glyphs as empty boxes mid-demo — so inside that application the
   field keys and formula builder render in Consolas by design, not by accident. */

   This used to be height:100%, which only resolves when the host gives its content area a
   definite height. The standalone harness does; WorxOrder_Enterprise does not, so there the
   shell grew to fit its content and every child that expected to scroll — the structure tree,
   the item details, the Try It filler — simply got taller instead. Selecting a field near the
   bottom of a long form then put its details off-screen above.

   --wo-chrome is whatever fixed header the host puts above this page. Both hosts use 56px, so
