/* WeightFrame - "The Forecast".
 * Energy balance read like a weather forecast: a night-sky Outlook panel holds the one number to
 * act on and the projection; everything else sits quietly on a cool mist ground. Amber is the
 * "you / now" marker, sky blue the projection, and the status colours follow a radar ramp
 * (green - yellow - orange - red - magenta, levels 0-4), always paired with a written label. */
