/* Mak Lyhour — staff app. Phone first; becomes a sidebar layout on the counter tablet/desktop.

   The system in one breath:
   - Ivory surfaces for everyday work, kept quiet so numbers are easy to read.
   - Ink panels with gold type are reserved for money that matters
     (the gold rate, the amount due). If it's dark, it's the thing to look at.
   - Noto Serif Khmer for titles and amounts, Kantumruy Pro for everything else.
     Khmer stacks vowels above and below the line, so sizes stay at 13px or more
     and line-height stays generous.
   - Colour in components always comes from the tokens below. */
