/* ---------------------------------------------------------------------
   tasklist — Manaurum Platform v2 sample

   Two voices, deliberately:
     · human  — the task text. The largest type on screen. There is no
                headline; the content is the display type.
     · machine — every piece of chrome (state bar, telemetry rail) is
                monospace, small, and quiet.

   Accent is gold, from the aurum in Manaurum. It appears in exactly
   three places: the composer's focus state, a completed checkbox, and
   the keyboard focus ring. Completion is otherwise expressed by
   typography — muted ink and a rule drawn through the text — not by
   adding a second colour.
