 * Sinduri theme — Solar design system.
 *
 * Palette:
 *   Solar        #f9c000   Primary accent, CTA bands, tags
 *   On-surface   #1c1b1b   All text, borders, frames
 *   Bone         #fcf9f8   Page base, nav background
 *   White        #ffffff   Cards, form fields
 *   Surface low  #f6f3f2   Subtle section backgrounds
 *   Surface high #e6e3e2   Layout structure only — NOT for visible borders (fails 3:1)
 *   Border       #8e8a87   All visible borders and dividers (3.27:1 on bone, 3.42:1 on white)
 *
 * Font: Lexend (self-hosted woff2, weights 400–800)
 * Wide logo: /circle-logo.svg  (1920×1080, use in banners and Canvas components)
 * Icon logo: /favicon-circle.svg  (circular mark, use in nav and favicon)
 *
 * WCAG 2.2 contrast audit (all pairs verified):
