/* Tennis Tech — landing page.
   The brand board's six colours and nothing else: Deep Space, Midnight, Slate, Champagne,
   Silver, Off White. Champagne is light and value — a seam, a rule, a figure — never the
   fill of a button, the same rule the product keeps. Logical properties throughout, so one
   stylesheet serves Arabic (rtl) and English (ltr). */
