You are the lead designer. Originate ONE complete, opinionated, buildable art direction for a website. I will implement it exactly, then put it through an independent design critique, so be concrete and commit.

THE SITE: A multipage marketing website for "Arizona Computer Guru" (ACG), a Tucson managed-IT and cybersecurity company since 2001. Differentiator: "concierge IT" (genuine relationships, going far beyond typical IT companies, transparent honest pricing, kind and direct, local). Audience: Tucson small-business owners, often burned before by surprise bills, offshore call centers, three-year lock-ins. The site sells trust first. Pages: Home, Services, Pricing, Calculator (interactive IT-cost estimator), About, Contact.

HARD CONSTRAINTS:
- Hand-built static HTML/CSS/vanilla-JS, driven by CSS custom-property design tokens. So give me CONCRETE values.
- Must be genuinely premium and distinctive, and must NOT look like generic AI-slop SaaS (no blue/purple gradient blobs, no floating 3D isometrics, no glowing shields, no hero-metric template, no identical icon-card grids).
- ALL text must be readable (WCAG AA, ~4.5:1 body) in BOTH a light theme AND a dark theme.
- It must be DISTINCT from the two skins this site already has: (1) "Sonoran Ledger" = warm cream paper, ledger rulings, mono numerals, burnt-amber accent; (2) "Midnight Concierge" = cool slate dark-premium with amber accent. Do not give me a third variation on warm-paper or cool-slate. Go somewhere new.

DELIVER, in this structure:
1. NAME.
2. CONCEPT: one tight paragraph. Name a real-world reference object/aesthetic so it is not generic.
3. COLOR TOKENS, explicit hex, for BOTH modes. Give exactly these roles for LIGHT and for DARK: paper (bg), surface, surface-2, ink (primary text), ink-2 (secondary), ink-3 (muted), rule (hairline rgba), accent (the one signal color used <=10%), accent-ink (the accent as TEXT, AA-safe on that mode's bg), on-accent (text on an accent fill). Keep chroma sane at extremes. State the accent hue you chose and why (you may keep ACG's amber or pick a new brand-justified color).
4. TYPOGRAPHY: display + body + mono families (real Google Fonts). You MAY change from the current Barlow Condensed / Lexend / JetBrains Mono if your concept needs it; justify. Note weights and the hierarchy approach.
5. SIGNATURE MOVES: 2-4 concrete, distinctive treatments that define the look (what replaces ledger rulings, corner radius, dividers, the way pricing/the calculator are framed, motion). Be specific enough to build.
6. IMAGERY: describe the hero image + 2 section images you want (photographic, so I can generate them with an image model), and the overall art-direction of photography (light, palette, mood). Say if existing warm golden-hour Tucson photos (desk-with-ledger, handshake, stucco storefront) should be reused or replaced.
7. ANTI-SLOP: 3 specific reasons this will not read as AI-generated, and name the single biggest risk that it DOES, plus how to avoid it.

Keep it tight and decisive, under ~750 words. Commit to specifics; do not hedge with ranges.
