   Tabler's fixed-width `.container-xl` (capped at 1140px/1320px+ at larger
   breakpoints). Both `_navbar.html` and `base.html` use `.container-xl` for
   consistent left/right gutters, so overriding its max-width here (rather
   than removing the class from two templates) keeps that gutter/padding
   behavior while removing the centered-column cap everywhere at once. */

/* ---------- Consistent page-section rhythm (UX audit, FR-87) ---------- */
/* Tabler's own `.page-header` rule only sets a top margin
   (`.page-wrapper .page-header { margin: var(--tblr-page-padding-y) 0 0 }`)
   and leaves zero bottom margin, so the gap before the first card/row on a
   page ended up depending on whichever ad-hoc utility class (`mb-3`, `mb-4`,
   none at all) that page's first section happened to use — inconsistent
   from page to page. This normalizes the vertical rhythm for every page
   built from base.html's `{% block content %}` (a direct child of
   `.page-body`), so authors don't need to hand-pick a spacing utility for
   section-to-section gaps — only for spacing *within* a section (row
   gutters, card internals) does a manual utility still make sense. */

/* ---------- Page header: title + actions side-by-side (UX audit) ---------- */
/* Tabler's `.page-header` defaults to `flex-direction: column` — correct
   for its *real* markup, where `.page-title` and `.page-actions` are meant
   to sit inside their own `.row > .col` / `.col-auto` wrapper. Every
   page-header in this app instead puts `.page-title` and `.page-actions`
   directly under `.page-header` (no row/col wrapper — see leads/list.html,
   leads/kanban.html, customers/detail.html, communications/thread.html,
   reports/dashboard.html, accounts/admin/user_list.html), so they stacked
   vertically with almost no gap on every page that has action buttons,
   while title-only pages looked fine — an inconsistency across the app
   rather than within one page. This makes that plain two-child structure
   behave like Tabler's row/col version everywhere, without having to
   hand-wrap six-plus templates individually. */
