/*
 * Bayla product UI: shared design tokens and components.
 *
 * One accent (blue) for primary actions, active states and key data only;
 * neutral grays for everything else. Strict 4px spacing grid, Inter at
 * 13-14px, 1px borders over shadows, 6/8/12px radii, flat fast controls,
 * motion under 200ms with no overshoot. Linked by the admin dashboard, the
 * customer portal and the demo storefront so all three read as one system.
