For my thrown weapons application. Could you please develop a profile page. That profile page should have the ability to set the username/display name, and should provide some details about their performance. Specifically some overall stats (Total Throws, Total Number of Sessions, Average of best 5 scores in the last 6 months, plot of moving average of session scores), Personal Bests (Highest Session score, Highest Session Event score ( Royal Round: score range 0 - 180)) Implement Preference plot, Practice Frequency Plot (like the github contribution plot)

I'll create a comprehensive profile page for your thrown weapons application! This will include an editable username section, detailed performance statistics, personal bests tracking, and visual charts including a GitHub-style practice frequency heatmap. The page will have a modern design with cards, gradients, and responsive layouts.

Analyze the following errors and fix them:

• Icon 'ThrowIcon' not exported by 'lucide-svelte'
• Uncaught Error: https://svelte.dev/e/effect_update_depth_exceeded

I'll fix those errors right away! The first issue is that ThrowIcon doesn't exist in lucide-svelte, so I'll replace it with ZapIcon. The second error is caused by a reactive loop in the preference plot - I'll refactor it to calculate the angles properly before rendering.
