Is your feature request related to a problem?
The card title is hardcoded (e.g. "CommitPulse" or the username). Users who embed the card in org READMEs or team pages want to set a custom label like "Team Streak" or "Q2 Contributions".

Describe the solution you'd like
Add a label URL param that replaces the default card title text.

Describe the solution you'd like

Proposed Solution

• Accept label as a string param (e.g. ?label=Team+Streak)
• Render it as the card's title text element in the SVG
• Max length: 40 characters — truncate with ellipsis if exceeded
• Sanitize the value to prevent SVG injection (escape <, >, &, ")
• Default: current title behavior when label is omitted

Example usage

Checklist

• label param accepted and sanitized
• Renders as SVG title text
• Truncated at 40 chars with ellipsis
• Default title preserved when omitted
• No SVG injection possible
