     6. TOOL                  — .tool card, segmented tabs, drop zone, buttons
     7. FILE ROW              — uploaded-file pill
     8. COMPRESS CONTROLS     — .opt-cards level pickers
     9. SPLIT CONTROLS        — chips, ranges input, page thumbnails grid
    10. RESULT BLOCK          — post-compress success card
    11. SECTIONS              — "How it works" steps + features grid
    12. FAQ + FOOTER          — (FAQ markup lives in faq.html)
    13. PRIVACY BANNER        — small pill above tool
    14. RESPONSIVE            — tablet (≤980) + phone (≤720)

   When porting: keep class names stable, replace tokens to rebrand.
