/* ============================================================
   oao.co — site styles, v0.1
   Builds on tokens.css (Brand Book v3.2). No new colours, no new
   type sizes: everything comes from the tokens.

   Layout idea: the page is the brand film, re-told in frames.
   Each story beat is one 16:9 still with a script-style slug line,
   then the copy on a 12-column grid. The page stays black, white
   and grey; colour only arrives inside the film's own images,
   when the signals do.
