/**
 * Calculator Result Stage — Phase F of /root/COMAU_AWARD_DESIGN_PLAN.md.
 *
 * Wraps the existing #full-results region so when the user clears the
 * email gate, the result lands as a designed moment rather than just
 * unhiding a div. The stage is opt-in: a wizard adds class
 * "calc-stage" to its full-results section and the CSS + JS apply.
 *
 * Choreography (the actual reveals are GSAP-driven from
 * /js/components/calc-result-stage.js — these are the layout +
 * starting states only):
 *   .stage-headline → number first (visible at t=0)
 *   .stage-summary  → +300ms
 *   .stage-breakdown rows → +500ms staggered
 *
 * Sage ring around the headline number is an SVG drawn via the
 * stage component; this CSS positions it.
