/* =====================================================================
   A2+ Design — PROJECT TIMELINE
   Sibling to the Planning Board: same wordmark, same Inter, same
   light/dark discipline. Its own accent, and its own way of showing
   work — bars against dates rather than task cards.

   The rule this file follows: one job, one device. Status is a dot,
   progress is a bar, structure is a hairline. Nothing says the same
   thing twice.
