   HELP CENTER — restyled to match the Settings hub design system
   (flat iOS grouped-inset look, no glass/blur, no rainbow gradients)
   plus a real desktop layout instead of a fixed 480px phone frame.

   Drop this in place of the original <style> block. Same HTML, same
   class names, same JS — only the visual tokens and layout changed.
