/* ============================================================================
   Altaha — Charts tab
   ----------------------------------------------------------------------------
   Every colour here resolves through the tokens already defined in index.html
   and premium.css, so the workspace inherits dark mode, reduced motion and the
   gold/ink/paper identity without restating any of it. Nothing in this file
   introduces a new hue.

   The one deliberate departure from the rest of the site: this screen is a
   workspace, not a document. It runs edge-to-edge, it does not scroll, and the
   tools live on a vertical rail on the left the way an instrument panel does.
   A reader scrolls; an operator reaches. The layout follows the verb.
