   Neo Leaf — neoleaf.co.th

   Colour and type are taken from the two live Neo Leaf sites, not invented:
     neoleaf-manufacturing.com   navy #0e1b4d · mint #00d49e
     neoleaf-products.com        navy #081831 · mint #00d49e
   Both share the mint. The navy differs between them; this site follows
   products.com's #081831 because it is also the exact fill of the mono
   emblem artwork, which makes it the defensible one of the two.

   Every value is authored in :root and nowhere else, so correcting the
   scheme is a one-file edit.

   Mainlux Light — self-hosted from the .woff2 already served by
   neoleaf-products.com's own CDN, so this is the same licensed webfont the
   products site uses rather than a desktop font pressed into web service.

   unicode-range is load-bearing, not an optimisation. Mainlux contains 372
   glyphs: Latin only, with NO Thai and NO Cyrillic. Declaring the range stops
   the browser trying Mainlux for Thai or Russian text and sends those
   characters straight to a font that can actually render them.
