/* =====================================================================
   ลมนนท์ แอร์เซอร์วิส — one-page concept site (fictional brand)
   Palette: paper white / sage mist / sand / slate ink / night LCD
   Type: Noto Sans Thai (condensed display + body) + Chakra Petch (figures)
   Motion: one reveal config (0.9s, cubic-bezier(.22,1,.36,1), once),
   one load sequence in the hero, everything else answers the visitor.
   Signature: the price calculator — physical keys, rolling LCD total.
   No animation libraries, no blur, transform/opacity only.
