/* LiveSquad by ConsultingThai · livesquad.consultingthai.com
 * Theme: TikTok-inspired. Near-black #010101 / #121212, white, cyan #25F4EE + pink #FE2C55 accents,
 * offset cyan/pink "glitch" shadow as the signature. Clean white sections for contrast.
 * Fonts: Inter (Latin) + Noto Sans Thai. Mobile-first, no build step.
 * Contrast notes: cyan / #FE2C55 are used as text only on dark backgrounds (13.6:1 / 5.1:1).
 * On white, accent text uses --pink-ink (#D90F3C, 5.1:1) or --cyan-ink (#00706c).
