/* ============ EXPERIMENTERS PAGE — PAGE-LOCAL STYLES ============
   The React app (#root) renders into a .exp-page wrapper. This CSS was
   authored against a rich local token set (--bg/--surface/--accent/etc).
   The block below REPOINTS those locals to the editorial design tokens
   defined in pb-chrome.css (var(--ink/paper/accent/...)), so the whole
   surface follows the paper(light) / cyber(dark) prefers-color-scheme
   system via [data-theme]. Scoped to .exp-page so it doesn't leak.
