/*
 * Launchloft v2 — "Modern Editorial Tech"
 *
 * Design direction:
 *   - Editorial bones (paper + serif + amber) keep the data-credibility tone
 *   - Bold tech elements: gradient hero, dark contrast section, glowing numbers,
 *     subtle grid + grain, hover micro-interactions
 *   - Stripe / Resend / Linear-influenced, but warmer (we serve indie creators,
 *     not enterprise SaaS buyers)
