 * gradients + grids, sticky toolbars, the legal/article doc headers) must
 * break out of that box: negative side margins span the full viewport while
 * the inner `.sx-container` keeps content centered at 1200px.
 *
 * This rule is the ONLY place the breakout is declared. New full-bleed
 * sections opt in with the `.sx-bleed` utility class — do NOT re-declare
 * `margin-*: calc(50% - 50vw)` in a page stylesheet. The page-specific
 * classes listed below are existing heroes/headers grandfathered into the
 * utility. Enforced by tests/test_sx_bleed_breakout_contract.py.

 * so the breakout never introduces a horizontal scrollbar. */
