   HOSUN · HERSTAR — Canton Fair kiosk, daylight skin
   The look is the approved brochure cover (Image_20261020221117_701_268.png)
   and HOSUN_spreads_v4.pdf: a peach-to-sun gradient, ghosted HOSUN letters,
   the H mark as a watermark, white spec cards ruled in sun orange.
   The Halloween layer lives in rising.css and only overrides tokens + a few
   surfaces under body.rising.
