“Stone” is closest to the website draft you liked — warm background, lighter text weight, hairline borders, far less grey.
How this becomes real: once you pick a direction, the change lives almost entirely in shared/shared.css (the design tokens — background, ink shades, border, radius, shadow, heading weight). Because every page reads those tokens, restyling flows through the whole ERP without touching each page. I can also wire it as a switchable theme (like the existing pink theme) so it's reversible.
