/* variant-a.css — chillygeek-faithful
 * Surface: Decide / Learn. Single hero, two CTAs, agent card grid.
 * Visual posture: borrowed (cyan→purple gradient on focal points, Inter,
 * dark base) but the layout, section weight, and copy are written for
 * Hermes-A2A — not a copy of chillygeek's content.
 *
 * Slop audit (out of 10; 0 = clean):
 *   1. Tech gradient ............ partial (h1 word + .btn-primary only;
 *                                   NOT on background or surfaces)          -> 0.5
 *   2. Generic tech hue ......... yes (cyan→purple is the chillygeek brief,
 *                                   but tell fires; would replace with
 *                                   amber/green if not constrained)     -> 0.5
 *   3. Feature-tile grid ........ no (cards are domain objects, not features) -> 0
 *   4. Accent rail .............. no                                          -> 0
 *   5. Unearned blur ............ no (header is solid #111218, no blur)       -> 0
 *   6. Monument stat ............ no (the "N agents" is a sentence, not
 *                                   a banner)                                  -> 0
 *   7. Icon topper .............. no (icons live inside connect cards, not
 *                                   above section headings)                    -> 0
 *   8. Center stack ............. no (hero is left-aligned, max-width 880px)   -> 0
 *   9. Default type ............. yes (Inter is the deliberate chillygeek pick;
 *                                   tell fires but is constrained by brief) -> 0.5
 *  10. Wrong surface ............ no (this IS a Decide/Learn page)            -> 0
 *  TOTAL = 1.5 / 10
 *  Repair needed: tell 5 (header glassmorphism) was fixed by switching to a
 *  solid background. Tells 1, 2, 9 are constrained by the brief (chillygeek
 *  brief = cyan→purple gradient + Inter).
