/* mudah. console
   Operate mode (console): restrained, precise, dense where useful. Persuade mode (sign-up): bolder.
   Tokens: primitives -> semantic roles. One UI family (Plus Jakarta Sans, tabular figures); Poppins only in the logo.
   Elevation is declared once (border, no shadow). Icons are line SVG, never emoji. Bars use one validated teal step
   per mode. Status always pairs colour with an icon and a label. */
