📊 AUCTION SCENARIOS

[✓] SCENARIO 1: Target Reached (≥10,000 TON)

Success! All participants receive TPING tokens.

If demand ≤ supply:
• Everyone gets tokens at final price
• No refunds needed
• Example: 10K TON raised → 5M TPING distributed

If demand > supply (Oversubscribed):
• Pro-rata distribution applied
• You get: (your_bid / total_raised) × 5M TPING
• Excess TON refunded automatically
• Example: 15K TON raised, you bid 100 TON
  → You get: (100/15000) × 5M = 33,333 TPING
  → Cost: 33,333 × final_price = ~27 TON
  → Refund: 100 - 27 = 73 TON back

[✗] SCENARIO 2: Target NOT Reached (<10,000 TON)

Auction Failed. Full refund to all participants.

• NO tokens distributed (allocated_tping = 0)
• You receive back: your_bid - 0.01 TON (gas fee)
• Refunds processed automatically via distribute endpoint
• Example: You bid 50 TON → get back 49.99 TON
