   ASIAKAS: Länsi-Helsingin Kirjanpito Oy — pohja demo6 (hiusviiva-ruudukko)
   Tyyli: vaalea, hieman sininen tausta + hillitty ammattimainen sininen aksentti.
   Neliskanttiset muodot (radius 0), ohuet hiusviivat, ei varjoja. Simppeli, konservatiivinen.
   Polut SUHTEELLISIA. Osiot: matriisi-palvelut, numeroidut rivit, hinnastotaulukko, Q&A.
   ----------------------------------------------------------------------------
   TEEMA VAIHDETAAN VAIN TÄSTÄ :root-lohkosta. Aksentti vaihtuu yhdestä muuttujasta.
