 * base.css — EBS Ads Dashboard shared design system
 *
 * This file is loaded on every authenticated page. It defines the colour
 * tokens, component primitives (platform nav, buttons, tables, modals,
 * toasts, badges, form fields) and a small set of utilities.
 *
 * Templates may still embed their own <style> blocks for page-specific
 * tweaks. Inline styles win against this file thanks to CSS source order,
 * so adding the <link> is a no-visual-regression change.
 *
 * When migrating a template to "shared-only" CSS, delete the lines from
 * its inline <style> that this file already provides, and lean on these.
