  /* m1 (2026-07-07 synthetic-user-testing, Marisol) — a SECOND, more severe
     bug found live-verifying the visibility fix below: `.mkt-hero` is
     `position:relative` (a positioned box) and sits later in DOM order than
     this header, so per CSS painting order (positioned elements paint over
     static siblings, and among positioned elements with z-index:auto, later
     DOM order wins) it was painting OVER the header's own `position:fixed`
     mobile nav overlay too — confirmed live: even with the OPEN nav's
     visibility/opacity/pointer-events all correctly "on", a real Playwright
     click on "Sign in" still hit the hero <img> underneath and timed out.
     An explicit z-index here (position:relative to make it apply, since
     z-index is a no-op on static elements) makes the header + everything
     inside it — including the fixed-position mobile nav overlay it
     contains — win that stacking comparison unconditionally, on every
     marketing page that has a hero. */

  /* §6 (2026-07-08 marketing elevation): breakpoint raised 767px → 1023px so the
     flat horizontal bar shows ONLY at ≥1024px (where the 6 nav items + Sign in
     fit inside the 1200px container) and the hamburger overlay covers everything
     below — six items overflow the flat bar between ~768–1000px. Same mechanics,
     wider range: every stacking/visibility fix documented below now simply
     applies over a wider band (more coverage, not less). The paired
     `.pub-container` gutter query stays at its own 599px breakpoint.

     m1 (2026-07-07 synthetic-user-testing, Marisol) — two real, distinct bugs
     at 375px, both confirmed live with Playwright before/after:
     1. CLOSED-state hit-testing/tab-order: the closed nav is
        `position:fixed;inset:0;top:64px`, so its layout box spans from right
        under the header down through the marketing hero — invisible
        (opacity:0) but still really there. `pointer-events:none` already
        stopped it from swallowing a tap, but it stayed hit-testable/
        focusable by anything that queries "the Sign in link" directly
        (assistive tech, automation) instead of tapping the hamburger.
        `visibility:hidden` (paired with a 0-duration, end-of-transition
        delay so the existing fade/slide plays identically) makes the closed
        nav genuinely inert — out of hit-testing, out of tab order — while
        `.open` flips it back instantly.
     2. OPEN-state stacking (the more severe one — found by actually driving
        the click after fixing #1, not by inspection): `.mkt-hero` is
        `position:relative` and sits later in DOM order than the header, so
        per CSS painting order it painted OVER the header's own
        `position:fixed` open nav too — a real Playwright click on "Sign in"
        still hit the hero <img> underneath and timed out even with the nav
        fully visible/enabled. Fixed at the source (`.pub-header`'s own
        z-index, above) rather than here. */
