     The page is built to read like the paper people actually work from in a
     studio: a script and a rundown sheet. Cool paper stock, ink, ruled lines,
     and exactly one red — the tally lamp — which appears only where something
     is live or timed. No dark "darkroom" base (silvergrainlab), no warm
     paper/amber (atelier-wehrle), no navy/teal ops palette (nipponatm). */
