Facet: the girl sat at the table with the old book open, pen held above the wide edge of a page. Nyra had written that page in a spring long gone. Now beside those lines the girl was setting down a few words of her own, small and careful, out at the margin where the paper stayed bare. Record carried by two hands down one page.
Continuity locks held: girl nameless; only Nyra named; British spelling; DIAL double-quote dialogue. Title-lock on main HTML. Haiku 4.5 and Gemini 3.8 Flash both flagged the prime serve live.
