/*
 * journal: design brief (mckennaiimushrooms.com)
 * 1. Concept: a scientific journal issue and specimen catalogue devoted to one cultivar. The home page is the
 *    contents page of an issue; every article is a short paper.
 * 2. Type: STIX Two Text (scholarly serif, text and titles, true italic) + Barlow Semi Condensed 500/600
 *    (technical labels, tables, numbers). Self-hosted woff2, latin + latin-ext.
 * 3. Palette: white paper #ffffff, abstract tint #f2f6f5, ink #141414, grey #545a5c, rule #cfd6d5, one teal #0b6767.
 * 4. Layout signature: tabular contents index (no., paper + abstract, reading time, sources), Figure 1 plate,
 *    abstract box, numbered sections (1, 1.1), captioned tables, superscript citations and a numbered reference list.
 * 5. Finishing detail: double journal rules (heavy over hairline) and products as catalogue entries "Cat. DS-2778".
