/* ========================================================================== Alterity.pl (Microsoft 365) — design tokens Light is default. Dark is opt-in via [data-theme="dark"] on . Shadcn-aligned variable names + legacy aliases for backward compatibility. BRAND ADAPTATION — "Palette Option B" (same family, Microsoft context): • Base navy comes from the actual Alterity logo/brochure: #0C0D47. • The teal `\` slash stays the family signature (decorative --accent). • The INTERACTIVE colour (buttons, links, focus) shifts from the cyberalterity dark-teal to a Microsoft-adjacent azure (#1466B8), so the site reads "Microsoft ecosystem" while remaining unmistakably part of the Alterity family it shares with cyberalterity.pl. Every interactive colour below was re-measured for WCAG AA (≥4.5:1 text). ========================================================================== */ /* ---------- Self-hosted Manrope (variable font, weights 200–800) ---------- */ @font-face { font-family: "Manrope"; font-style: normal; font-weight: 200 800; font-display: swap; src: url("../fonts/manrope/manrope-latin-ext.woff2") format("woff2"); unicode-range: U+0100-024F, U+0259, U+1E00-1EFF, U+2020, U+20A0-20AB, U+20AD-20C0, U+2113, U+2C60-2C7F, U+A720-A7FF; } @font-face { font-family: "Manrope"; font-style: normal; font-weight: 200 800; font-display: swap; src: url("../fonts/manrope/manrope-latin.woff2") format("woff2"); unicode-range: U+0000-00FF, U+0131, U+0152-0153, U+02BB-02BC, U+02C6, U+02DA, U+02DC, U+0304, U+0308, U+0329, U+2000-206F, U+2074, U+20AC, U+2122, U+2191, U+2193, U+2212, U+2215, U+FEFF, U+FFFD; } :root { /* ================================================================= LIGHT MODE (default) White-base, navy text, teal slash accent, azure interactive. ================================================================= */ /* Surfaces */ --background: #FFFFFF; /* page canvas */ --card: #FFFFFF; /* cards (drop shadow elevates from muted) */ --muted: #F5F8FC; /* section backgrounds, large surfaces (very light azure-grey) */ --secondary: #EFF6FB; /* azure-tinted surface for accent regions */ --popover: #FFFFFF; /* Text on each surface */ --foreground: #1A2D5C; /* navy — primary body text; AA huge on white (12.9:1) */ --card-foreground: #1A2D5C; --muted-foreground: #5A6678; /* mid-slate — captions; AA on white (5.83) + on --muted (5.6) */ --secondary-foreground: #1A2D5C; --popover-foreground: #1A2D5C; /* Interactive — Microsoft-adjacent azure (AA on white: 5.8:1) */ --primary: #1466B8; /* azure — buttons, links, focused state */ --primary-foreground: #FFFFFF; --primary-hover: #10559C; --primary-active: #0C4680; --primary-soft: rgba(20, 102, 184, 0.10); /* Accent (decorative — brand teal as-is, the `\` slash colour; non-text) */ --accent: #1FB6C1; /* brand teal — family signature */ --accent-foreground: #06373B; /* Status */ --destructive: #E25555; --destructive-foreground: #FFFFFF; --warning: #8B4F0F; /* deep amber — AA on white (6.6), --muted, --secondary */ --success: #1E8A5F; /* Borders + form inputs */ --border: #E4EAF2; /* subtle separators (decorative — no WCAG floor) */ --input: #CFD8E3; /* legacy form-border alias; retained for decorative use */ --border-input: #7E8FA2; /* form-input border. slate-blue, navy-family.
