Letters — the series, as designed

Cover Seesaw House. Beige gradient, Lexend setup top left, plum duotone photograph filling the slide beneath it, closing cue bottom right on a cream plate. The photograph starts where the setup text ends, measured per post.
Letter Cream ruled page, 56px rule pitch, Source Serif sitting on the rules. Long letters run onto more slides, split only between paragraphs. The last letter slide carries the closing cue.
Closing Deep plum, facts only, the last line the one that changes the letter.
Two things to keep in view The closing cue adds words that are not in the letter, which the brief did not ask for. Every photograph is a placeholder with no rights cleared, and post 6 has none at all.
