    Blueprint SVG router. Takes $category (string) and renders matching blueprint.
    Used as fallback featured image on blog cards + article hero.

    Category → blueprint map:
    - platform-mechanics → vault
    - tools-guides       → exploded
    - announcements      → rings
    - anything else      → rings (safe default)
