 * The visual world is the shop drawing, not the yacht club: lofting tables,
 * chalk lines, blueprints, marine ply. Deliberately not navy-and-rope coastal
 * nautical.
 *
 * System fonts only, by choice -- these pages get read on a phone in a shed
 * with two bars of signal, and a webfont round-trip is the wrong tax. Georgia
 * carries the long-form entry prose; a condensed stack does title-block work.
