/* ==========================================================================
   Sổ Bán Hàng Hoa Nam Khánh — shared mockup stylesheet (tokens + components)
   Visual contract for app/tenants/hoanamkhanh. Plain CSS, no remote assets.

   Identity: "đồng và than chì" (copper + graphite). The trade sells copper
   conductor wire and pipe; the shop counter is lit by white fluorescent tubes
   and the person at the keyboard reads numbers fast while a thợ waits. So:
   pure white work surfaces, cool graphite ink, one copper action colour, a
   sparing teal ("nước") second accent, hairline rules, right-aligned figures.
   Type: IBM Plex Sans (UI, data) + IBM Plex Mono (codes, document numbers).
