/*
 * Boot background — applied before the app bundle loads so the window never
 * flashes an unstyled background on cold start. The inline script in
 * index.html overwrites this with the cached theme color once ThemeProvider's
 * state is available; on first-ever launch it falls back to this black default.
 *
 * Kept as a linked stylesheet (not an inline <style>) so that Tauri's
 * build-time asset processing does not inject a nonce token into this element.
 * Tauri nonces inline <style> elements and adds the corresponding 'nonce-…'
 * source to style-src at runtime; per the CSP spec a nonce in a directive
 * causes the browser to ignore 'unsafe-inline', which would block TipTap's
 * runtime stylesheet injection and emoji-mart's shadow-root styles in packaged
 * builds. The inline boot script is SHA-256 hashed (not nonced) — that path
 * only applies to scripts, not stylesheets.
