Learned from a strong example prompt (not reused verbatim — different
subject, same technique): a stop-motion/hand-animated look wants
irregular timing, but true unseeded randomness breaks HyperFrames'
determinism guarantee (same seek must always render the same frame).
The correct pattern is a PRNG seeded once at composition start, stepping
elements between held positions rather than tweening continuously —
distinct from rule 1's continuous ambient idle, which is a different
tool for a different texture.
Kept separate from "The grammar, measured" (rules 1-6, empirically
videoed) since there's no rendered proof for rule 7 yet — the new
section and example are illustrative, not claimed as verified.

Validates 16 more published prompts end-to-end (variants across every
video type, caption styles, overlays with proven alpha, code diff and
highlight, edit verbs against the real attribute map, a generated-avatar
talking-head through embedded-captions, a presented slideshow deck) and
fixes every prompt flaw the builds surfaced. Adds keyword-to-render
grids for the easing, camera, and marker vocabulary; two more worked
visual specs with renders; a measured before/after pair proving the
motion grammar (frozen frames vs all-alive, 211KB vs 2.5MB); before/
after render pairs on editing and generated-artwork pages; and proof
renders on the overview.

Five-way review of the section against docs.json, catalog pages, and
skills. Fixes: stale /hyperframes-media skill row (real name /media-use)
plus missing music-to-video and slideshow workflow rows; caption
identity misattributions (keynote/documentary are scene-embedded, stomp
carries no rail); prompts violating the guide's own ambient-idle rule;
grounded keying rationale (u2net_human_seg); broken forward references;
nested-backtick code spans; brand casing and frontmatter dash
consistency throughout.

Splits guides/prompting into a Prompt Guide nav group (overview + Fundamentals
+ Making it look good, 11 pages) with a redirect from the old URL. Applies
research-validated upgrades: beat content formula, before/after prompt rewrites
with engine rationale, single-variable iteration moves, absolute-target
calibration, camera/depth/pacing vocabulary, prerequisites gate.
