  /* ── Page shell geometry ───────────────────────────────────────────
     One source of truth for the content column, shared by the header
     (nav / .nav-inner) and every page shell, so the two can't drift.

     --hub-content is the column itself: the logo's left edge to the
     account pill's right edge. --hub-gutter is the viewport inset.

     .nav-inner carries no padding, but `* { box-sizing: border-box }`
     means a page shell's max-width INCLUDES its padding — so a shell
     has to be --hub-content PLUS both gutters to end up with a
     --hub-content-wide content box. That is --hub-shell-max. Setting a
     shell to --hub-content directly lands ~2*gutter too narrow. */
