/* Platform chrome: the navbar and footer shared by the portal and every tool page.
 *
 * These rules used to be copied into portal.css and into each tool's stylesheet. The
 * copies drifted: the portal rendered "AI TOOLS" at 0.9rem/700 with no shadow while the
 * tool pages rendered it at 1.25rem/900 with one, so moving between the two pages looked
 * like moving between two products. This file is the single source of truth - the page
 * stylesheets must not redefine any selector below. tests/test_platform_chrome.py checks
 * that, and checks that every page links this file.
 *
 * Self-contained on purpose: portal.css and style.css declare different palette
 * variables (--border vs --slate-200, --primary vs --slc-orange-primary), so the chrome
 * carries its own --chrome-* set and renders identically whichever stylesheet follows it.
