/* ==========================================================
   neur0doku-shop.css
   Layout for the shop screen only. Colors come from
   neur0doku-theme.css — nothing here should hardcode a color
   or reach for a site --token. Self-contained: this page loads
   neur0doku-theme.css + neur0doku-components.css (for
   .nd-icon-btn) alongside this file, so the .nd-tabs/.nd-tab-btn
   rules here are a standalone pill-toggle, same pattern as
   neur0doku-quests.css — not a dependency on any modal-tab styling.
