/* DeskDude access gate.
   Same direction as the rest of the site: premium utilitarian minimalism,
   warm monochrome canvas, off-black warm ink, muted pastel feedback,
   serif headline, flat 1px-bordered card.
   Tokens mirror styles-about-rebuild.css so the gate reads as part of
   the site rather than a separate screen.
   Motion is restrained: one gentle entry, and small acknowledgements. */
