/* ---- Primary navigation -------------------------------------------------
   Single-row, 72px-tall premium header: logo left, evenly spaced charcoal
   dropdown triggers centered, and a light "Call" pill + primary "Get Started"
   button grouped on the right. CSS-only dropdowns on native <details>/<summary>:
   every link lives in the HTML source (crawlable); CSS only hides/reveals and
   positions the floating panels. No JavaScript is involved.

   Spacing baseline (per the header redesign spec): 28px nav gaps, 40–48px
   nav-to-actions gap, 12px phone-to-CTA gap, dropdowns floating 14px below
   their trigger. The desktop nav never wraps to a second row — below 1024px it
   collapses to the mobile/tablet header. */
