   Concept: before software, every trades business in Thailand ran its day off a
   whiteboard by the office door — rows are technicians, across is time, magnets
   are jobs. That is the language the customer already reads, so the site is
   built out of it rather than out of SaaS-marketing furniture. Cobalt-on-white
   with a floating drop-shadowed screenshot — the default for this category — is
   avoided entirely: the palette is signal yellow and asphalt, the colours of a
   service van and a hi-vis vest.

   Signature: the dispatch board (.board). It is real CSS Grid with real markup,
   not a picture of a product. On first load one unassigned job drops into the
   free technician's row — the product demonstrated in two seconds without a
   single sentence of copy.

   There is not one photograph on this site. That is the decision, not an
   omission: the product is a screen, and a stock photo of a smiling technician
   would say nothing.
