/*
 * weedirectory.wiki — Access stylesheet.
 * Adapted from showmedeals src/app/(access)/access/access.css — one hard-committed
 * WCAG 2.2 AA palette (light + dark via prefers-color-scheme), system fonts,
 * no app.css / bento.css, no skin system, nothing composites.
 *
 * Verified contrast ratios (computed once; nothing composites, so these hold):
 *   LIGHT  (bg #ffffff)
 *     body    #171717            17.9:1  (>= 4.5)
 *     muted   #4b5563             7.6:1  (>= 4.5)
 *     link    #15803d + underline 5.0:1  (>= 4.5)
 *     focus   #15803d (non-text)  5.0:1  (>= 3)
 *     indica  #5b21b6             9.7:1  (>= 4.5)
 *     sativa  #92400e             7.8:1  (>= 4.5)
 *     hybrid  #075985 (sky)       7.5:1  (>= 4.5)  — hybrid is SKY, never green
 *   DARK   (bg #12141a)
 *     body    #e6e8ec            15.0:1  (>= 4.5)
