 * LIGHT — Lab for Innovation in Global Health Technology
 * V4 — the beam
 *
 * ─── THE BEAM ────────────────────────────────────────────────────────────────
 * The wordmark's diagonal slice, measured off the logo artwork itself:
 *
 *     letter   run      drop    angle
 *     L         51.36    2.30   2.564°
 *     I         51.33    2.30   2.566°
 *     G         82.14    3.68   2.565°
 *     H        181.64    8.14   2.566°
 *     T         51.06    2.27   2.546°
 *                              ────────
 *                        mean   2.561°   (spread 0.02° — one deliberate cut)
 *
 * So: --beam-angle: -2.56deg, and --beam-rise: 4.47vw (tan 2.56° × 100vw), which
 * holds the exact angle at every viewport width instead of only one.
 *
 * The beam does the work that generic decoration used to: it is the section
 * divider, the emphasis mark, and the edge on every dark band. Used at most once
 * per screenful — a signature repeated everywhere stops being one.
 *
 * ─── DELIBERATELY ABSENT ─────────────────────────────────────────────────────
 * No italic serif for emphasis. No letter-spaced uppercase eyebrows. No ticker
 * bar or pulsing dot. No rounded-rectangle card grid, hover-lift or drop shadow.
 * No pill buttons. No · separators. No → glyph on every button. These are the
 * house style of AI-generated layouts; the beam replaces them.
 *
 * Type is one family (Archivo) at varying weight. Palette is the seven approved
 * brand colours — see tokens.
