/* ==========================================================================
   RSS Feed Dashboard — "Nightwire" palette
   --------------------------------------------------------------------------
   Thesis: the dashboard has no house colour. One calm ink family carries the
   whole interface; the only saturated colour belongs to the sources
   (YouTube / Reddit / RT) and is used strictly as a signal — filter pills,
   card spines, chips, timestamps, feed health.

   Rule for every filled state: bright fill, deep ink type.
