/* IXCHEL TRAVEL — C2 "Seoul, Edited" shared sub-page system.
   Loaded AFTER /assets/site.css on every sub-page (guide, quiz, about, review,
   thank-you, privacy, quiz results). Reproduces the approved homepage design
   system so the whole site reads as one publication. The HOMEPAGE keeps its own
   inline C2 styles and does NOT load this file — nothing here touches it.

   Values are lifted verbatim from the live homepage (index.html inline <style>).
   No new brand colours; no rounded SaaS cards, gradients, or heavy shadows. */
