Adds 18 pages completing the Prompt Guide expansion (phases 2-4): six
video-type pages seeded by the verified example prompts, and twelve
feature pages giving prompting guidance for surfaces the docs implied
but never covered (transitions, caption styles, overlays, code blocks,
data/maps, VFX, rendering/output, editing existing videos, media/audio,
variables, runtimes/3D, design systems). All block/component/skill names
grounded against the catalog and skills; render pairing deferred.
