/**
 * Katie Rae Photo — front end.
 *
 * Design note. The palette is taken from water rather than from a template:
 * a cold deep-water ink, the grey-green of sea haze, foam off-white, and a
 * single patrol yellow borrowed from surf lifesaving flags. The yellow only
 * ever appears on focus and active states — it is the one loud thing, and it
 * is loud on purpose so keyboard users can always find themselves.
 *
 * The signature is the horizon: a hairline rule that runs the full width
 * under the wordmark and reappears above the footer. Surf photography is
 * built around that line, so the page is too. Gallery metadata hangs off it
 * in mono, set like a session log.
