That detection used to rely on hardcoded prefix checks; it now first checks a general list of open\/tail\/end marker pairs, falling back to the old prefix-based check only if none match.\n\n**Why**\n\nThis is an internal restructuring of how collapsed content is recognized, making it easier to add new collapsible content types without touching the fallback logic. It shouldn't change what a user sees.\n\n- Area: Elsewhere\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 1\/5"}
