The kinetic-letter-in motion-primitive (a music-to-video reference authors copy) animated the word's letterSpacing as a settle — a reflow tween that micro-stutters under seek-by-frame capture, and outside the registry scan so the rule never fired on it. The chars are already per-glyph spans, so migrate the settle to a per-glyph x spread ((0.04em − −0.04em) × 280px = 22.4px/gap, centered about index 3), with a comment naming the hazard and the rule. Render-verified: faithful, smooth. Document two intentional design choices in gsap_non_transform_motion so future readers don't read them as misses: - No per-line/per-file suppression by design — the stance is fix-the-motion, not silence-the-rule; every plain-DOM case has a faithful transform equivalent. - set() is skipped intentionally: a set() that seats an integer-snapped layout position before a later transform tween is a single from-state frame, not motion. Also hoist loadParseGsapScript() above the per-script loop (the other async rules do the same; dynamic-import cache makes it equivalent, but the placement no longer reads as load-bearing).
