   Qubiq AI — site styles (single hand-written file, no framework)

   Look: light, calm, editorial. Warm paper background, ink text,
   one accent (indigo -> violet). Dark blocks are used for contrast.
   Kept from the Robor layout: giant uppercase headline, floating
   nav pill, cut-corner (clip-path) cards and buttons.

   CONTENTS (search for the section title)
     tokens ........ :root colours, fonts, sizes
     base .......... reset, typography, .container, .section
     shapes ........ .cut / .cut-bl corner cuts, buttons
     header ........ nav pill, logo, burger, mobile drawer
     hero .......... aurora, grain, headline, product stage, badge
     marquee ....... scrolling capability strip
     (legacy v1) ... .cards/.card and .principle(s): no longer used on
                     the home page (replaced by bento / pcards below);
                     safe to delete if you do not need them
     process / use cases / engagement / faq / cta / footer
     reveal ........ scroll-in animation (.reveal -> .reveal.in)
     responsive .... breakpoints 1080px and 720px
     inner pages ... page hero, prose, values, services, posts, form
     v2 ............ language switch, service detail, articles,
                     Chinese typography overrides (html[lang="zh-CN"])
     bento ......... the four coloured service cards + SVG animations
     v3 ............ principles, process cards, cases, plans, faq,
                     big service blocks, detail/about components

   Rules of thumb
     - Colours live in :root; do not hard-code new ones if a token fits.
     - Anything animated has a prefers-reduced-motion fallback near
       the "reveal" section.
     - Add Chinese-specific sizing under "Chinese typography".
