   Direction: Vietnamese (Lii Lash family) — mint/teal accent on warm white, near-retail
   polish kept at 2B factory trust density. NOT DTC.
   Standing bans (bridge/CLAUDE.md): no gradients, no emoji, no pill badges,
   no GREEN CTA (CTA = ink), no pure-white wash, no "beautified" WhatsApp bubble.
   teal = brand/section accent ONLY. */
