   H2 Intelligence - dark tech / terminal
   Theme: dark only (brand decision). Accent: electric blue #2563EB

   Two accent tokens, on purpose:
     --accent      #2563EB  fills only (buttons, dots, bars, mesh, glow).
                            3.85:1 on #09090b, so NEVER use it for text.
                            White on it is 5.17:1 - that direction passes AA.
     --accent-text #60A5FA  7.83:1 on #09090b. Every accent-coloured TEXT,
                            small label and thin (1-2px) stroke uses this.
