 * Sponsor placement — rendered by core/templatetags/ad_slots.py when a
 * SponsorPlacement record is currently active for the requested ad slot.
 *
 * Design goal: clearly distinct from editorial content (the "Sponsored"
 * label must be obvious, the visual treatment must not be mistaken for
 * a regular pull-quote or callout), but still on-brand (gold accent,
 * editorial typography). Honors editorial-separation: looks like a paid
 * placement, never like part of the article body.
