/* ==========================================================================
   The Veil Archive — Reader Hub (V1, visible layer)
   --------------------------------------------------------------------------
   Rebuilt for V1. Deliberately contains NO styling for points, levels, ranks,
   streaks, achievement badges, challenges, or notification popups — those UI
   concepts were removed. This stylesheet dresses the honest progress model:
   an intro banner, first-action cards, an exploration bar, a Codex grid, a
   record-reader modal, milestone chips, a recent-activity list, and settings.

   Uses the site design tokens from main.css (--color-*, --space-*, etc.).
