Build error: Color(r:g:b:) is a private extension scoped to DesignTokens.swift
(only UIColor's sibling init is also private, both file-scoped by design).
KC-55/56 called it directly from SettingsView.swift and OnboardingView.swift
for the coffee icon color -- invisible there, so the compiler fell back to
unrelated overloads ('Cannot convert Int to Color', 'Extra argument b').
Added AppColors.coffeeBrown (defined where the private init is visible),
replacing both inline Color(r:g:b:) call sites -- matches how every other
color in the app is centralized and accessible everywhere.
