/**
 * layout.css — structural scaffolding for the Jouman theme.
 *
 * Containers, the main wrapper, grid helpers, stack/flow utilities and the
 * section spacing scale. Structure only: no colour beyond what a wrapper
 * genuinely needs, no component styling (see components.css).
 *
 * RTL: every directional value uses a logical property (margin-inline,
 * padding-inline, inset-inline-*, border-inline-*, text-align: start/end).
 * There is no `left` or `right` anywhere in this file, which is precisely why
 * the theme needs no rtl.css and no `direction` declaration.
 *
 * Mobile-first only. Breakpoints: sm 480 / md 768 / lg 1024 / xl 1280.
