    ██║███████╗██████╔╝     1% buy tax / 1% sell tax — HARD-CAPPED at 1%
    ██║╚════██║██╔══██╗     Taxes can be lowered or zeroed, NEVER raised.
    ██║███████║██║  ██║     No blacklist. No max-wallet traps. No mint.
    ╚═╝╚══════╝╚═╝  ╚═╝     Trading, once opened, can never be paused.

    ── DEPLOYMENT (Remix) ──────────────────────────────────────────────
    1. Add Stable Mainnet to MetaMask:
         RPC:      https://rpc.stable.xyz
         Chain ID: 988
         Symbol:   USDT0 (gas is paid in gUSDT)
         Explorer: https://stablescan.xyz
    2. In Remix: compiler 0.8.20+ , optimizer ON (200 runs).
    3. Deploy with constructor args:
         router_    = the Uniswap-V2-compatible router on Stable chain
                      (pass 0x0000000000000000000000000000000000000000 if
                       you don't know it yet — you can create the pair
                       later with createPairWithRouter).
         taxWallet_ = wallet that receives the 1% tax (in ISR tokens).
    4. If you passed a router: the WGAS/ISR pair is created automatically.
       Add liquidity on the DEX (you are fee-excluded, so this works
       before trading opens).
    5. Call openTrading() — this is ONE-WAY and enables everyone to trade.
