/* Pre-paint guard (set by the inline boot script in index.html when a
 * valid OAuth runtime token is in localStorage). Reveals the dashboard
 * on the very first paint so the user never sees a blank/login flash
 * on refresh. The full app.js init then hydrates real data underneath.
 * Inline style="display:none" attributes have higher specificity than
 * this rule, so we use !important — the inline JS will swap them
 * properly once init runs. */
