Add Shilpa Yoga Space single-page site (HTML/CSS/JS) and update README

[amanratnam]

Motivation

• Provide a clean, single-page portfolio site for Shilpa Yoga Space to showcase services, programs, testimonials, and contact details.
• Centralize editable content so updates can be made without changing markup by using a single data object siteContent in script.js.
• Deliver an aesthetic, responsive layout with light interactive polish (parallax layers and CTA links) for a modern presentation.

Description

• Add index.html containing semantic sections (hero, about, services, programs, testimonials, contact, footer) and placeholders for dynamic content.
• Add styles.css with a complete theme, responsive layout rules, card and grid components, and visual system variables for colors and spacing.
• Add script.js that defines the siteContent object, populates the DOM (services, programs, testimonials), wires up mailto:/tel: links, sets the footer, and implements a simple mouse-parallax effect for layered elements.
• Replace the original README with README.md describing the project, quick start instructions, and guidance to update content via script.js.

Testing

• No automated tests were added or run for this change.
