/* LightPlane brand — the one stylesheet the public pages share: /welcome and
   the sign-in card (/index.html).
   Values come from /welcome, which set the look (2026-10-21). /box and /legal
   use the same palette and type. The boot screen in /ai/index.html repeats the
   tokens inline because it must paint before any stylesheet arrives — change
   them there too.

   Type: Sora for the wordmark and headings, Inter Tight for everything else.
   Wordmark: the trapezoid + "Light" regular + "Plane" bold, all white. Never
   colour "Plane" and never set it in another face.
   Pages load the fonts themselves (Google Fonts link), so this file never blocks
   on a third-party @import. */
