/* Product marks (Danny 16/10/2026): each product looks like its own space at a glance, inside design kit v1.
   No new colour: the glyph sits on an ink tile in the one orange; the product's own rule (its motif) replaces the
   plain separator under its header. Shared by Backstage (index.html) and the conversation page (fight.html). */
