/* FIELD COMMS: an intentionally local mock, layered over the existing game HUD (js/ui-chat.js).
   Restyled 2026-10-09 (direction A "Field Terminal", Proposed): the launcher and the side panel are HUD plates
   (base.css ::before, --c1/--c2 cuts, --bd, --fill, --deco); text in IBM Plex Sans Thai, labels in Chakra Petch,
   counts and times in Oxanium; channel colours stay per channel (--channel from ui-chat.js). Only the input takes
   text selection; the log scrolls inside the panel (contained, thin bar). No backdrop blur over the live canvas. */
