Primary UI uses crafted SVG icons, never clipart/emoji; color is reserved for state, not for buttons.
Decision (operator, June 2026): primary and structural UI uses CRAFTED SVG icons (stylish, on-brand), NEVER default plain emoji or clipart. Emoji is acceptable only as a playful inline accent (for example the call-intent chips in a popup), not as primary iconography.
Corollary on the shared business card: card overlay icons are neutral white on the dark translucent circle; color is reserved for STATE (a saved heart is red, a checked-in pin is green), never for the buttons themselves. Tried colored outlines, reverted — color-as-state reads better and scales as more actions are added.
Same family of taste calls as no dark patterns and Design Standards: the product should never look cheap or machine-stamped.
