/* ============================================================================
   BLOOM — Attribution tree (DAG) styling
   ----------------------------------------------------------------------------
   Owns the member-facing lineage DAG on the record page (Propagation section).
   The tree lives on warm, identity-facing record pages, so nodes use the
   whimsy `.win` treatment: 22px radius, white rim, soft offset shadow. Typed
   edges are color-coded by CC branch (Adaptation = green, Remix = teal,
   Collection = gold) AND labeled, so type is never conveyed by color alone.

   The SVG is now the PRIMARY visual (no longer aria-hidden): it carries a
   role/label and its nodes are keyboard-reachable links. Below it, an
   equivalent accessible NESTED LIST (`.lintree__fallback`) restates the whole
   lineage as text — required by the global "every chart needs a table/list
   fallback" rule. Colors come only from badges.css tokens (defined inline in
   commons/index.html's :root); no off-palette hex.

   Loaded AFTER the page's inline <style>, so these rules win where they repeat
   the legacy `.lin*` selectors that used to live inline.
