/* Layout concept: a clinical "chart recorder" page — a full-width signal strip up top, then a single 1080px column where
   each section pairs a short argument with one exhibit (chart or diagram). Three fixed signal colours carry EEG/ECG/EMG
   identity everywhere; a single deep teal is the page accent; alert red is reserved for the alarm state. */
