Refine portfolio copy and add Services & Process sections

[ForgetFullness]

Motivation

• Improve the landing copy and hero details so the portfolio reads as a clear, service-oriented offering with availability highlighted.
• Expand the single-page layout to include running services and an explicit process to better communicate deliverables and workflow.

Description

• Update index.html with refined hero text, an availability badge, updated stats, and clearer CTAs, plus new Services and How I work (process) sections and minor contact/footer tweaks.
• Update styles.css to slightly tune the light palette and add styles for .availability, .stats, .services, .service-card, and .process-steps, including responsive adjustments.
• Small navigation text changes and copy improvements across About, Projects, Skills, and Contact sections to present a cohesive portfolio voice.

Testing

• Launched a local static server with python -m http.server 8000 and the site served successfully on the forwarded port (server started successfully).
• Attempted to capture a full-page screenshot with a Playwright script, but Chromium crashed in this environment so the screenshot step failed (Playwright BrowserType.launch / SIGSEGV).
