   Typography
   ---------------------------------------------------------------------------
   Three families, each with a job. All are system fonts: this app holds
   privileged material, and a webfont CDN would leak a request revealing which
   tool the firm is using, on every page load.

   --font-ui    Interface: labels, tables, buttons. A humanist sans.
   --font-read  Sustained prose: assessments, summaries, the chronology. A
                serif is easier on the eye over paragraphs of narrative.
   --font-mono  Verbatim document text, Bates numbers, dates. Monospace does
                two jobs here: it preserves the column alignment that
                `pdftotext -layout` produces (tables, signature blocks), and
                its glyphs keep 1/l/I and 0/O apart — which is the difference
                between reading a Bates number or an amount correctly off an
                OCR'd page and misreading it.
