/* Kestrel marketing site styles - v0.13.2 / Phase 0.
 *
 * Brand palette anchored on the desktop app's chrome: deep navy as the
 * trust colour, warm orange accent for CTAs and the AI sparkle motif,
 * off-white surface. Sans-serif system stack for performance + zero
 * font-loading flash. Phase 5d will polish copy + add screenshots; this
 * is the structural baseline.
