/* Atomic Shelf — editorial library (/editorial/*).
 *
 * A separate file from editorial.css on purpose. editorial.css is part of the
 * frozen production baseline and is loaded by the home page, Services,
 * Pricing and the rest; this task must not be able to alter it. The new pages
 * load both, and everything below is scoped to classes that exist only here.
 *
 * Colours and type are inherited from the baseline's own tokens rather than
 * restated, so the library stays on-palette if those tokens ever move.
