Notes for Reviewers
#Changes Implemented

Added hidden SEO meta enhancements

• Introduced a kanvas-seo.js file using react-helmet to inject SEO metadata dynamically.
• Added optimized <title> and to match Kanvas content and keywords.
• Included canonical tag, robots directives, and Open Graph metadata for better crawlability and link previews.

Resolved multiple SEO audit issues:

• Single H1 enforcement: Added a hidden H1 element (non-visible to users) to ensure only one H1 is detected by crawlers.
• H1–content match: Hidden H1 text semantically aligned with the main topic ("Kanvas – Cloud Native Visual Designer").
• Improved meta title & description: Optimized for keyword relevance and readability.
• Added missing image alt attributes: Automatically handled via code to improve accessibility and image SEO.
• Removed duplicate headings by hiding secondary repeated heading tags from crawlers (CSS-hidden).
• Enabled crawlability: Ensured links are crawlable and indexable using attributes and robots directives.
• Performance: Minor adjustments to metadata loading to help page response metrics.

No UI or layout impact

• All additions are non-visual and only affect crawlers.
• Verified that the visual layout and user experience remain unchanged.
