/* Acidus — an ISO 17025 testing laboratory on Marcus Garvey Drive, Kingston.
 *
 * Idiom: the datasheet. A lab is not sold on photographs; it is sold on three
 * numbers a client actually asks for — is this test inside your accredited
 * scope, how long does it take, and what does it cost. So the page is the
 * board that answers them: the four disciplines with their turnaround, then
 * every test with its method, its accreditation mark, standard and rush time,
 * price and what to send. No stock photograph of a beaker: the only pictures
 * are of the material the lab actually tests — Kingston's concrete.
 *
 * Composition: the board is the first screen. Not a headline over a photograph
 * and not a hero — a poster of the lab's operating state, the four disciplines
 * and their turnaround typeset as the thing you came to read, the way a lab
 * pins its turnaround on the wall by the sample window.
 *
 * Palette: cool steel grey, graphite ink, and one cobalt. A testing lab spends
 * its authority on one distinction — what is inside its accredited scope and
 * what is not — so cobalt, a reagent blue, marks exactly that and nothing else:
 * an accredited method, an in-scope figure. Everything else is ink on steel.
 * No warm tone anywhere; a lab that looks reassuring is hiding something.
 *
 * Type: Golos Text, a neutral grotesque, for every word, and Spline Sans Mono
 * for every figure — a method number, a turnaround, a price, a job reference —
 * so the page reads as the instrument printout it is.
