/*
 * String Explorer guided string finder (/string-explorer).
 *
 * Ported faithfully from the legacy tool (ernieball/public/assets/css/
 * string-explorer.css): a teal field with the hand-drawn yellow "STRING
 * EXPLORER" wordmark on the left and the wizard on the right — wide yellow
 * option pills each paired with a separate yellow (i) info segment, and
 * orange/red BACK + START OVER controls.
 *
 * This page keeps its own teal/yellow/red identity (not the site pink). Page-
 * namespaced BEM (.string-explorer__*); the legacy brand colors live in the
 * page-local custom properties below.
