React 0.13.0

Added

• Saved appearance. The theme, colours and pricing table options a merchant saves in the Nozle dashboard (Developers > Customize SDK) reach every component without code. BillingProvider reads meta.sdk_appearance from the plan catalog request (GET /api/v1/plans), the same cached request PricingTable and usePlans use, so a page makes one call. The saved theme, variables and planCardLayout are the lowest layer: appearance on BillingProvider and on a component win. With nothing saved, or when the request fails, no variables are written and the components look as before. Pass savedAppearance={false} on BillingProvider to never fetch or apply it.
• PricingTable takes highlightStyle, highlightLabel (an empty saved label means no badge), annualDiscountLabel and showToggle from the saved options when the props are unset; props win.
• The SDK reads only a closed schema: a theme name (light, dark, minimal, neobrutal, nozle, nozleDark), colour variables as #rgb or #rrggbb, radius and width variables as px, rem or em lengths, planCardLayout, and the four pricing table options. Anything else is ignored, so a saved value never writes free CSS.
• PlanCard takes isUpgrade, with the same button states as PricingTable.
• Saved appearance for a single component. The dashboard can save a theme, variables, card layout and pricing table options for one component (components.<Name> in meta.sdk_appearance, for example PricingTable or UsageMeter). They apply to that component only, above the saved global appearance and below appearance on BillingProvider and on the component. A component rendered inside another (a UsageMeter in UsageDashboard, an UpgradeModal in UpgradeButton) uses its own saved settings.

Changed

• Plan buttons follow the current plan. Without a current plan every plan (except contact sales, which stays outline) gets the primary button, with the theme's buttonShadow, and the highlighted plan keeps its highlight colours. With a current plan, plans above it get the primary button, the current plan gets the primary colour without the shadow, and plans at or below it, a highlighted one included, get the secondary button. Before, only the highlighted plan was primary when there was no current plan. In the panel layout the "Active" label of the current plan takes the primary colour.
• BillingProvider requests the plan catalog (cached, never retried, errors not shown) unless savedAppearance={false}, also on pages that only use components such as UsageMeter.
