/* px_ui / mar_preview_html: the MAR chart preview pane's stylesheet,
   head-linked from anvil.yaml native_deps.head_html.

   Every rule is scoped under .px-mar-preview. Colours are --px-* tokens only,
   with no var() fallbacks. The host owns the zone around the pane (the sticky
   column and the breakpoints); the pane fills the zone's width and sets a
   default height that a host may override with its own rule on
   `#<zone> .px-mar-preview { height: ... }`. */
