Build a Bio Page with Chatbot

I want to build a personal "link in bio" page and deploy it to GitHub Pages.

My details:
- Name: [Your Name]
- Title: [Your Title at Delinea]
- A short tagline or bio: [e.g. "Bridging the gap between cybersecurity and business — one demo at a time"]
- Links to include:
  - Calendar: [Your booking URL]
  - LinkedIn: [Your LinkedIn URL]
  - Company website: https://delinea.com

Please:
1. Create a clean, modern single-page HTML/CSS site with my info and links
2. Include Delinea company logo branding on the page (pull the logo from delinea.com)
3. Initialize a git repo
4. Create a GitHub repo named [your-github-username].github.io using the GitHub CLI
5. Push the code to main
6. Enable GitHub Pages on the repo

Now let's enhance the site with the following improvements:

1. Dark/light mode toggle button that switches between themes and
   remembers the user's preference
2. Animated entrances for all elements on page load (fade or slide in)
3. Hover effects on all link cards (lift effect, subtle color/shadow change)
4. A favicon and descriptive page title that reflects my name and role
   - Important: create the favicon as a separate SVG file (e.g. favicon.svg)
     rather than an inline data URI — inline SVG favicons often render as
     a black square in browsers.

Make sure everything still looks clean and cohesive after these changes.

Let's add a live page view counter to the site using Cloudflare Workers KV.

1. Create a Cloudflare Worker that increments and returns a visit count
   stored in KV on each page load
2. Add a KV namespace binding to wrangler.toml
3. Display the count on the page in a subtle, styled way
4. Make sure the counter works in both dev (wrangler pages dev) and
   production (Cloudflare Pages)

Let's add an AI chatbot to the site that acts as a virtual version of me.
The chatbot should use the Anthropic Claude API (claude-haiku-4-5), and the
API key must never appear in source code — it gets fetched at runtime from
Delinea Secret Server using OAuth2 client credentials.

Here's what I need:

**1. Cloudflare Pages Function — functions/api/chat.js**
- POST endpoint that accepts { messages: [{role, content}] }
- Rate limit to 10 requests per minute per IP
- On each request:
  a. Use DELINEA_CLIENT_ID and DELINEA_CLIENT_SECRET (from env) to get an
     OAuth2 bearer token from:
     https://[DELINEA_TENANT].secretservercloud.com/oauth2/token
  b. Use that token to fetch the Anthropic API key from Secret Server:
     GET https://[DELINEA_TENANT].secretservercloud.com/api/v2/secrets/[DELINEA_SECRET_ID]/fields/password
  c. Call the Anthropic Messages API with Claude Haiku and the system prompt below
  d. Return { reply: "..." } as JSON

**2. System prompt — make it personal**
Write a system prompt that instructs the AI to BE me in first person, not
describe me in third person. Include:
- My name: [Your Name]
- My role: [Your Title at Delinea]
- My background: [2-3 sentences about your experience and what you work on]
- How I talk: direct, no corporate fluff, explain technical things simply
- What I can discuss: my background, PAM/cybersecurity topics, what it's
  like to work with me
- Always point people to book a real conversation for deep dives

**3. Chat widget — floating button + slide-up panel**
- Fixed position, bottom-right corner of the page
- Chat bubble button that opens/closes the panel
- Panel shows conversation history, a text input, and a send button
- Show a typing indicator ("...") while waiting for the AI response
- Handle errors gracefully with a user-facing message
- Style it to match the site's existing dark theme and color palette

**4. wrangler.toml**
Add the required KV namespace binding for CHAT_LOGS (create the KV namespace
via wrangler if it doesn't exist) so chat interactions are logged.

**5. Environment variables needed in Cloudflare Pages Settings → Variables and Secrets:**
- DELINEA_CLIENT_ID (Secret)
- DELINEA_CLIENT_SECRET (Secret)
- DELINEA_TENANT (Plain text — just the subdomain, e.g. mycompany)
- DELINEA_SECRET_ID (Plain text — the numeric ID of the secret in Delinea)

These are already set in Cloudflare from step 8 of the setup guide — the
Worker just needs to read them from env.

After wiring this up, test it locally with:
  wrangler pages dev . --binding DELINEA_CLIENT_ID=test

The goal is a working chatbot where a visitor can ask questions and get
responses that feel like they're talking to me — and where the API key is
demonstrated as a live runtime secret fetch, never hardcoded.
