TAMARIND CAESAR — DESIGN SYSTEM
"Premium Thai Contemporary": deep espresso brown, caramel/gold, cream, white.
One stylesheet, shared by every page (Home, product & article detail
pages, and the LINE/Facebook/TikTok/Maps demo destination pages) so the
whole site reads as one consistent brand — not a collection of loose
HTML files. Organized top to bottom in the order a browser will meet
these rules: tokens → base/type → buttons → layout chrome (header,
footer) → page sections → components (cards, media frames, specs,
demo screens) → motion → responsive breakpoints.
