/*
 * VALDIER V3 — compact smart navbar.
 *
 * Sizes: 80px at the top of the page on desktop (48px logo), 66px on compact
 * widths (40px logo, 48px menu button); away from the top, [data-nav-compact]
 * turns it into a 50px bar (32px / 28px logo). Colours, links and the mobile
 * menu stay as exported.
 *
 * Smart, once per trip away from the top: the navbar sticks to the top (the
 * announcement bar above it scrolls away as before). js/valdier-navbar.js
 * sets [data-nav-hidden] on the first scroll down, removes it 1.5s later, and
 * the navbar then stays visible until the page is back at the top.
 *
 * No layout shift: .nav_component keeps the height of the top-of-page bar in
 * the flow and only the bar inside shrinks; the strip left under the compact
 * bar is transparent and lets clicks through. Hiding is transform only.
 * Up in 220ms, back in 350ms, size changes in 250ms.
