/* Venn editor — a set circle is a real shape, so the core's default accent stroke reads well on it.
   A region label is a <text> glyph, so a stroke would look like a broken outline; highlight it by
   accent fill instead (pie pattern). The title and set labels are decoration, not pick targets — let
   clicks fall through to the circle beneath them. */
