Solana Academy — Transaction Cost Lab 01

Open transaction-cost-lab.html in a current browser. Keep the HTML, CSS, and
JavaScript files together. The calculation works offline; the linked official
references need an internet connection. It makes no RPC or wallet connection,
does not store answers, and does not sign or submit transactions.

The result is an educational estimate based only on the values you enter. It
is not a wallet quote or current network simulation. Refresh base-fee and
account-storage inputs from authoritative current sources before using them in
real transaction planning. V1 resource limits must be explicitly configured.
