CORE RULES

• Force a vertical 9:16 composition with 1080x1920 output intent.
• Treat the first 0-3 seconds as the hook window: close readable emotion, travel payoff, or immediate visual surprise.
• Keep the main subject centered enough for phone viewing; do not place important detail at extreme edges.
• Use bottom-third caption-safe space; faces and key action should sit above the lower caption band.
• Captions should be big, bold, white text with a black outline, under nine words when possible.
• Prefer 8-15 second pacing for LTX shorts unless the user explicitly requests another duration.

PROMPT ARCHITECTURE

• Start with the subject and immediate hook action.
• Specify vertical mobile framing before lens detail.
• Include caption overlay instructions only as design direction, not literal scene text unless captions are being rendered.
• Add retention language: fast emotional clarity, immediate payoff, simple silhouette, readable motion.
