/* Exceltior Live: design tokens and base components (company/brand-web-standards.md, adapted for app density).
   Type: Cormorant Garamond 500 for page titles and hero headings only (never below 20px or in tables), Inter for all
   interface text, JetBrains Mono for identifiers. Fonts are self-hosted: the app works offline and sends nothing to font
   CDNs. Cormorant Garamond could not be downloaded in the build environment: it is used when installed on the device,
   otherwise headings fall back to Georgia. To ship it, add CormorantGaramond-Medium.woff2 and -SemiBold.woff2 (Latin
   and Latin Extended, for Polish) to /public/fonts/ and a url() to the two @font-face rules below. */
