Superfluid S6 campaign dashboard -- data logic + presentation

[thalescb]

What this adds

Live campaign dashboard for the Superfluid SUP Rewards Season 6 campaign, fetching directly from the Superfluid Points API.

Architecture

• superfluid-api.js -- standalone data logic module (API client, reward calculations, data transformations). Pure JS, no DOM. This is the reviewable code.
• index.html -- presentation layer that imports the module. Dark mode, responsive, Chart.js charts.

Features

• Campaign hero with total allocation, participants, points
• Two pool cards (GD Actions 217,700 SUP + Ecosystem Funding 404,300 SUP)
• Campaign analytics: daily events chart, points distribution, cumulative participants
• Leaderboard with pagination (10/page), estimated SUP reward per wallet
• Reward calculator: paste address, see points + estimated reward
• How to Participate CTAs with links
• Season toggle: switch between S6 (live) and S5 (test data with 2,611 real participants) to verify logic
• Event caching across toggles

How to review

The data logic lives entirely in superfluid-api.js. Key functions:

• fetchCampaign(), fetchLeaderboard(), fetchBalanceBatch() -- API calls
• calculateReward(), calculateCombinedReward() -- reward math
• aggregateDailyCounts(), computeCumulativeParticipants() -- chart data

How to test

Serve locally with python -m http.server 8081 --directory projects/superfluid-s4/dashboard then open http://localhost:8081. Use the S5 toggle to see real data (campaign 511, 2611 participants).
