{#
  SETTINGS sub-tab placeholder (R4a). Rendered for the three tabs that aren't
  functional yet — Configure (R4c), Providers & Models (R4b), Cortex (R4c).
  Clean, labeled card stating the section + the increment it lands in. Reuses
  the prototype's `.set-stub` styling.

  Context:
    placeholder_label     : the tab's human label (e.g. "Providers & Models")
    placeholder_increment : the increment it's slated for (e.g. "R4b")
