/*
 * Stetworth — shared vertical-page stylesheet.
 *
 * Used by every vertical landing page (/legal, /private-equity,
 * /founders).  Loaded AFTER site/css/style.css, which owns the
 * palette, type scale, buttons, the review-record component, the
 * numbered `.steps` list and the modal.  Everything here is either a
 * component only the verticals use (the sign-off card, the task
 * table, the standing-rule pull-quote, the example cycler) or a
 * page-level arrangement of shared parts.  No token is redefined —
 * every value comes from the base stylesheet's custom properties, so
 * the vertical pages can never drift off-palette.
