/*
 * Heritage theme. Structure follows the Jcorp Mk4 theme (jcorp-nomad-push master.css):
 * sticky 64px header with a logo chip, 10–12px radius cards that lift on hover, tiles with a
 * press-down, the same shadow and easing tokens. Colours are a warm paper palette instead of
 * Jcorp blue; the navy Jcorp tree stays as the mark.
