/* eqlly — shared chrome (tokens / reset / nav / footer / document prose).
   Used by works.html and legal/*.html. index.html still carries its own inline
   copy: it is 1800 lines of interdependent CSS and the risk of refactoring it
   mid-flight outweighs the drift. Migrate index.html to this file the next time
   it is opened for structural work.
   The footer in particular MUST stay identical across pages — when the legal
   pages go live, the 準備中 markers here and in index.html both flip. */
