   A blank line marks the required entry (only V₁), like a blank on a form; the gate shows the same line, larger.
   Entered values read larger and bolder, like pilot entries in large font on a Boeing CDU; values from a source
   (METAR, NOAA, airport data) keep the regular weight with the source in blue. The gate stays green: computed. */
