/*
 *  GALLERY INDEX — Landing Page Explorations
 *
 *  THE IDEA
 *  A Swiss annual-report contents page. The versions inside all speak
 *  serif — Georgia, Palatino, Times, Cambria — so the index speaks
 *  Helvetica: the curatorial voice, not another exhibit. Tabular numerals,
 *  a hairline grid, copper squares as the only ornament. One device does
 *  the talking: each entry's name is set in the typeface of its own
 *  version, so the index doubles as a specimen sheet.
 *
 *  TYPE
 *  Helvetica Neue / Helvetica / Arial for everything structural — the only
 *  register none of the versions claims. Georgia, Palatino, Times New
 *  Roman, and Cambria appear only in the entry names, as specimens.
 *
 *  SCALE
 *  H1 clamp(2rem, 4.5vw, 3.25rem) bold, tight tracking. Entry numerals
 *  clamp(1.5rem, 3vw, 2.25rem) light, tabular. Entry names clamp(1.3rem,
 *  2.4vw, 1.75rem) in the version's own serif. Body 0.95–1rem / 1.6.
 *  Rules are all 1px hairlines; the only heavy mark is the copper square.
 *
 *  PALETTE (WCAG AA, verified)
 *  ink #181614 on paper #faf9f7 ......... 17.2 : 1
 *  muted #57534c on paper ...............  7.3 : 1
 *  copper #7f4329 on paper ..............  7.3 : 1
 *  faint #6b665e on paper ...............  5.4 : 1
