fix(client): count IconGaugeOutline16 in the icon-set pin; keep the hero headline text addressable

The icon-set spec still pinned 74 exports after IconGaugeOutline16
landed (a hand-drawn product glyph — the set is now eight of those).
Moving the preview badge inside the hero title group had merged the
headline into one text node with the badge, which broke exact text
lookup (hmr-live e2e); the headline gets its own span again.
