Stern military document typewriter letterforms — precise, utilitarian, official. Heavy uniform ink distribution, no decorative elements. Standard government issue typewriter. Letterforms reference 1942-era Remington or Royal military typewriter models. Dense black ink on off-white document paper. Clean mechanical spacing. Official military report aesthetic — every letter typed with bureaucratic precision. Classified document quality. No-nonsense wartime typography. Off-white government document paper, crisp and official, subtle watermark texture. Neutral overhead lighting, bureaucratic and precise. Perfectly centered layout, three tiers: Top: tiny "CLASSIFIED" in small caps, red-stamp weight but typewritten. Center: massive "OPERATION BLACKOUT" filling 72% of frame width, military typewriter weight. Bottom: small caps "TOP SECRET · EYES ONLY · DO NOT DUPLICATE", tight and formal. Vertical spacing 1:5:1. No ornamentation. Authority through restraint.
