/* Ethan Halland Photography — Meridian, from his own frames.
 *
 * §5 extraction on his 18 photographs returned a bright cool ground, a deep
 * near-black, a BROWN accent and a slate blue second. Two adjustments, both
 * from his own words:
 *
 *   "I enjoy earthy colors maybe as accents but overall looking for a brighter
 *    layout. Browns and greens I really like."
 *
 * So the ground stays bright — his references are white, not cream, and he asked
 * for bright explicitly. The brown accent is kept as extracted. The slate second
 * accent is replaced with a green, because he named greens and the extraction
 * found water and sky rather than the trees.
 *
 * EARTHY AS ACCENT, NOT AS GROUND. That distinction is his and it is the whole
 * palette decision — see REFERENCES.md.
 *
 * MEASURED against both grounds:
 *
 *   token     on --bg   on --surface
 *   ink        16.11       14.84
 *   muted       5.42        4.99
 *   accent      6.44        5.93
 *   accent-2    7.32        6.75
 *   on-deep    15.88  on --deep
