/* Sunshine Charity Society — sunshine.timebank.tw
   Component structure/behavior follows the WSI/CES Federated App Top Nav
   Contract v1 (km-base/01_Governance/CIS-Presentation-Tier) and the working
   reference implementation in wsi-website/src/assets/css/output.css.
   Color tokens and typography are sampled directly from Sunshine's own
   public identity: the actual logo asset (sunshine-charity-logo-*.png,
   pixel-sampled: orange #ff7900, red #dc0202, gold #fed500) and the
   source site's rendered fonts (Outfit for headings, DM Sans for body) —
   not WSI blue or an invented palette. */
