/* ============================================================================
 * Suunta.ai Landing v2 — FAQ  (V2 — premium minimalist rebuild)
 * ----------------------------------------------------------------------------
 * LIGHT. Accordion-list. Hairline-divider jokaisen itemin alle.
 *
 * V2 polish (käyttäjäpalaute "premium ja minimalistinen"):
 *   - Aiempi grid-template-rows -accordion-bug korjattu max-height-pohjaisella
 *     ratkaisulla joka mittaa scrollHeight:n dynaamisesti → animaatio menee
 *     täsmälleen sisällön korkeuteen (ei hard-coded max).
 *   - Plus → × rotaatio-icon (45° spring transform) chevron:n sijaan
 *     → Linear/Stripe modern premium pattern.
 *   - Isompi question font (17px), generosa padding (22px vertical).
 *   - Ei emerald-bg auki-tilassa — vain icon vaihtaa emerald-värin.
 *   - Ensimmäinen item open default → käyttäjä saa visuaalisen kontekstin.
 *
 * Ops styleguide:
 *   - Question: 500 medium, ei bold
 *   - Hairline-divider per item
 *   - Plus-icon: 14×14 + transform rotate(45deg) auki
 *   - Answer: prose-tyyli, secondary color

 * Initial state max-height: 0 → suljettuna. Open: JS sets exact px value.
