/* ============================================================
   Solon — the sales pages: home, pricing, about, the edition homes,
   the forthcoming placeholders and the practice-area pages.
   Loaded AFTER site.css / course.css and solon-v2.css. Colours come
   only from the tokens both of those define (--paper, --card, --ink,
   --line, --accent …), so light and dark themes follow by themselves.

   Written after the September 2026 funnel review, which found that on a
   390x660 phone the home page spent its first screen on a 175px sticky
   header and a 90-word lede, and never said who the library is for,
   what is free, or showed a single screen of the product.
   ============================================================ */

/* ---------- the header on a phone ----------
   Two short rows instead of three tall ones: the seal, the name and
   "Sign in" on the first; Library · Pricing · About on the second.
   About 76px instead of 175px. The tagline is hidden on phones only. */
