/*
 * logbook: mushroomgrowbox.org
 * 1. Concept: a grower's logbook / lab notebook. Warm paper with a faint graph grid, entries written up
 *    in graphite, one moss green for structure and links, signal orange only for warnings.
 * 2. Type: IBM Plex Serif for reading and titles; IBM Plex Mono for labels, step numbers, data and metadata.
 * 3. Palette: paper #f6f2e9, graphite #262624, pencil #5a574f, moss #47612a, signal #c25a1f (ink #9a3e17).
 * 4. Layout signature: every page is a numbered log entry with a metadata strip; h2 sections and ordered
 *    steps are indexed in a left rail (step boxes joined by a vertical line); tables read like log lines;
 *    blockquotes are orange warning slips.
 * 5. Detail: products as inventory slips with a mono stock reference; "end of log" rule under the footer.
