/* Paid-feature accent — premium, not broken.
   We deliberately *don't* grey these out. Greyed buttons read as "disabled
   for some reason I should figure out"; that's friction without intent.
   Instead we add a soft gold sparkle accent + a small "✨" badge so the
   feature reads as "this is a premium thing you can unlock" — the
   psychological lift between "broken" and "aspirational" is huge.

   Tapping still opens the upgrade modal (intercepted by the capture-phase
   click handler in the JS). Visible-to-everyone, accessible to paid users
   only — same pattern that Spotify, Notion, Linear, etc. all converged on. */
