   M-A-S-T-E-R.ai — design tokens (assets/css/00-tokens.css)

   GENERATED. Do not hand-edit. The build writes this file from
   brand/tokens.json; brand/tokens.json is the only place a token NAME and a
   token VALUE live together. See the never-printed gate: it reads its name
   list from that same file at run time, so a token added to tokens.json is
   guarded on the same build that ships it.

   This file must load BEFORE main.css and before every pages/*.css. It is
   the only file in the theme permitted to contain a colour literal.

   Structure is three-state on purpose:
     1. bare :root                                  -> light, always defined
     2. @media (prefers-color-scheme: dark)
          :root:not([data-theme="light"])           -> system dark, but an
                                                       explicit light choice
                                                       still wins
     3. :root[data-theme="dark"]                    -> explicit dark wins in
                                                       both directions
   Raw tokens are declared once, in :root. Only the SEMANTIC aliases are
   redefined in the dark states, so there is exactly one place a mode swap
   can go wrong.
