/* ──────────────────────────────────────────────
   Shared navigation styles for the marketing site.
   The nav markup is baked into each page's HTML (identical everywhere), so the
   header never reflows between pages. This file only:
     - keeps items on one line (no wrapping)
     - reserves the scrollbar gutter so pages don't shift left/right
     - collapses the nav into a hamburger on phones (nav.js adds the button)
   ────────────────────────────────────────────── */

/* Reserve space for the vertical scrollbar on every page, so navigating
   between a short page and a long one never nudges the layout sideways. */
html { scrollbar-gutter: stable; }
html, body { overflow-x: hidden; max-width: 100%; }

/* Neutralise per-page `nav a { margin-left }` so the header is identical on
   every page: the logo sits flush-left and link spacing comes only from the
   flex `gap`. Without this, some pages push the logo/links 40px right. */
header nav > a { margin-left: 0; }
/* Keep every top-level nav item on a single line, spaced only by the flex gap,
   at one fixed size so the middle items land in the same place on every page. */
header nav > div > a { white-space: nowrap; margin-left: 0; font-size: 0.95rem; font-weight: 500; }
