/* ---------------------------------------------------------------------------
 * sx-nav-actions.css
 * Top-bar enhancements for the Sigrix shell:
 *   - v2 (guest):  in-nav shopping cart button + popover
 *   - v3 (signed): credits chip, redesigned notifications popover,
 *                  Publish CTA, and user "pill" with stats dropdown.
 * Sourced from Sigrix Marketplace v2 / v3 design prototypes.
 * --------------------------------------------------------------------------- */

/* ---------- Base sx-nav chrome ----------
 * The structural top-bar styles (band, inner shell, logo, primary links)
 * live here rather than in css/sx-home.css so EVERY page that renders
 * components/sx_nav.html gets the styled top bar — including the
 * moderator/admin shells, which use a `shell-flush` body (no `.sx` scope)
 * and never opt into sx-home.css. The search, cart, publish, credits, and
 * mobile chrome already live in this file for the same reason.
 *
 * `.sx-nav-inner` folds in the layout-container box model (max-width /
 * centering / gutter) so the bar stays centred even where `.sx-container`
 * isn't defined, and `.sx-nav-link` / `.sx-logo` set `text-decoration: none`
 * directly instead of leaning on the `.sx a` reset that only ships with
 * sx-home.css. */

 *
 * On narrow screens the desktop bell / cart buttons can be small or off-axis,
 * so an `position: absolute; right: 0` popover ends up off-screen or visually
 * disconnected from the tile the user tapped. We use `position: fixed` so the
 * popover doesn't follow its anchor button's small bounding box.
 *
 * Caveat: `.site-header` and `.sx-nav` apply `backdrop-filter`, which creates
 * a containing block for fixed descendants. So `top: 72px` is measured from
 * the header's box, not the actual viewport — but because the header is
 * `position: sticky; top: 0` it stays glued to viewport y=0, which makes the
 * two coordinate systems coincide in practice. Anchoring via `top` (just
 * below the 60px header bar) gives a stable position regardless of scroll;
 * `bottom: 16px` would have measured 16px from the *header's* bottom edge,
 * placing the popover at the top of the page.
 *
 * The triggers' existing outside-click handlers (see sx_nav_cart.js and
 * notifications_bell.js) still close the popover, so no JS coordination is
 * needed — the change is presentation-only. */
