/**
 * BH Coastal — Components
 * ------------------------
 * Buttons only need two registers: a solid navy primary action, and
 * a quiet outlined/ghost secondary. No color-fill hover animation,
 * no shadow lift — restraint is the point. Both use the same wide
 * letter-spacing as nav labels so buttons read as part of the same
 * system, not a bolted-on UI kit.
