/* settings-card -padded surface card with two layout modes:
 *
 *   Default (padded stack)        ``.settings-card``
 *     Flex column, gap = space-3, padding = space-3. For forms with
 *     stacked ``.form-group`` children (label + input + help), or for
 *     a head + body block.
 *
 *   Row stack with dividers       ``.settings-card.settings-card--rows``
 *     Zero gap, zero padding on the outer card. Children are
 *     ``.settings-card-row`` elements (flex row, label on the left,
 *     control on the right) with a divider between each row. Used for
 *     toggle lists, threshold rows, summary read-outs.
 *
 * Name kept as ``.settings-card`` (not just ``.card``) to avoid a
 * prod-template sweep · the class predates this promotion and ships
 * across settings sub-pages, team management, recipes, POS chrome.
 *
 * Differs from:
 *   - components/13-card.css ``.c`` -bare card primitive, no flex
 *     layout, no row dividers.
 *   - components/51-card-block.css ``.card-block`` -labeled summary
 *     tile (smaller gap, no --rows mode). When the card decision gets
 *     revisited, these three may consolidate into one component.
 *
 * Composes with:
 *   - .form-group children (in default padded-stack mode)
 *   - .settings-card-row children (in --rows mode)
 *   - .settings-stepper (right-aligned inside a card-row)
 *   - .toggle-row / .switch (right-aligned inside a card-row, or as
 *     the only child of a default-mode card)
