Brand color refresh
The primary accent color has been updated from cool indigo (#4F46E5) to a rich, warm amber (#92400E in light mode, #FBBF24 in dark mode) across all design tokens, the logo, and the GitHub Pages documentation site.
Why this change? Indigo carried the aesthetic of a productivity tool — focused, corporate, digital. As Oikos has grown into a home for thousands of families, we wanted the visual identity to better reflect what the app actually is: a warm, shared space for everyday life together. Amber — deep and earthy in light environments, bright and inviting in dark ones — communicates exactly that. It evokes warmth, reliability, and the kind of unhurried intimacy that family life deserves.
From an accessibility standpoint, Amber-800 (#92400E) achieves a contrast ratio of 7.20:1 against white, exceeding the WCAG AA threshold and meeting WCAG AAA. The dark mode value (#FBBF24) maintains the same readability standard. The transition is purely cosmetic — no data, settings, or behavior has changed.
Logo: updated the gradient on docs/logo.svg and all inline SVG instances from violet (#8B5CF6 to #6C3AED) to amber (#B45309 to #92400E).
