/*
 * HuiDots main site — production stylesheet.
 *
 * Design tokens sourced from `huidots_tokens.json` v5.1.0 Direction A
 * (canonical brand spec; HDO-550; Owner-accepted 2026-09-14).
 * HDO-665 split the Direction A green into two roles:
 *   --green       brand-graphic accent  (preserved #7BC143)
 *   --green-text  foreground-text role  (#3F7A1B, a11y-derived for Paper)
 * CSS cannot natively import JSON, so the canonical values are pre-bundled
 * below and documented at the `:root` declaration. The JSON file remains
 * the single source of truth; any future token change must land there first
 * and then be mirrored into this block by the Web Engineer.
 *
 * HuiDots palette · Direction A v5.1.0:
 *   HuiDots Teal    #00A79D
 *   HuiDots Navy    #0D1117
 *   HuiDots Green   #7BC143   ← brand-graphic accent (HDO-665)
 *   HuiDots Green-T #3F7A1B   ← foreground-text role, a11y-derived (HDO-665)
 *   Paper           #FBFBFB   ← page surface
 *   Ink Soft        #2A3142
 *   HuiDots Mint    #B9E1D5
 *   HuiDots Lime    #D7E869
 *   Cinnabar        #B73E3E
 *   Saffron         #D89545
 *   Porcelain       #3A6FB5
