/* In-match text chat (Trello: "Implement text chat improvements").
   Every chat style lives in this one file so it can be matched to the card's
   design attachment in one pass - the layout below is the game's Timber &
   Brass language (timber.css) standing in until then.

   Two channels, two text tones:
   - global: white.
   - team:   a pale sage green. Deliberately NOT a team colour - yellow and
             blue read very differently over the scene, so both sides get the
             same tone, and it is clear of the yellow/blue name colours and
             the brass used for system notices.
   Selectors are #chat-box-scoped so they outrank the shared iron text-field
   rule in index.html's inline <style>, which loads after this file. */
