   outage.css — /outage/ (labs 557)
   -----------------------------------------------------------------------------
   The page's own sheet, loaded after the house sheet and before dark.css.
   Prefix ou-. TOKENS ONLY: every colour below is a house token (--ink, --line,
   --paper, --accent, --taken, --free, --unsure and their washes), so the dark
   edition is answered by the tokens and this file has no second half. Paper
   and dark are two skins of the one document; nothing here knows which is on.

   COLOUR IS NEVER THE ONLY SIGNAL. A drop is a number in words ("down 21%")
   with the age of its flag before it is a bar; the status in the console head
   is a word ("live", "kept copy", "no answer") before it is a colour; an open
   event in a history says "open at IODA", a closed one whose signal had not
   returned says "not back at close"; an IODA event on a chart is a hatched
   band named in the line under the chart.

   TOUCH. Every control this sheet styles is at least 44 px tall.
