/*
 * meter (penisenvymushrooms.com)
 * 1. Concept: a precision instrument panel. The site reads one cultivar the way a bench instrument reads a sample:
 *    labelled channels, dials, an LCD readout, a product slot in the rack.
 * 2. Type: B612 Mono (the Airbus cockpit-display face) for labels, numerals and headings; Golos Text for reading.
 * 3. Palette: bezel grey #d7dad3, panel face #f7f8f4, graphite #15181a, needle red #b3321a, lamp amber #d99a1c,
 *    housing #1c2023.
 * 4. Layout signature: home = instrument panel of server-drawn SVG dials, bar and range meters, a thermometer strip,
 *    status lamps and a product slot; articles = channel plate, four-cell spec strip, patch bay contents, and every
 *    h2 section in its own panel with a numbered tab (03.2).
 * 5. Finishing detail: corner screws on every panel and the hairline tick scale under the rack header.
