/* #start: how we start (four steps) and the Talk to us form. Copied from the approved Validator #start
 * (emable/apps/vbe-web/lp/sections/07-start/section.css): panel, rail motion, form, chips, consent, done state.
 * Changes: four steps instead of three, steps stay a vertical list on phones, no Q&A block.
 * Repo port (12 Nov 2026): name and company side by side (.st-row) and a message textarea (.st-ta).
 * Motion: the rail draws step by step after reveal (base.css pauses keyframes until .is-in); the final state is the base
 * style, so no JS, no .motion and reduced motion all show everything. */
