📝 Walkthrough

Walkthrough

Refactors Arweave URL fallback handling by introducing a prioritized gateway list and utility functions to validate and reconstruct URLs. Reworks the withArweaveFallback logic to sequentially attempt gateway URLs on failures while tracking state via data attributes.

Changes

Cohort / File(s)	Summary
Arweave Fallback Utilities components/nft-image/utils/arweave-fallback.ts	Introduces ARWEAVE_GATEWAYS constant and utility functions (safeParseUrl, normalizeHost, isArweaveGatewayHost, getGatewayIndexFromUrl, buildUrlWithGateway) for gateway URL handling. Refactors withArweaveFallback to validate Arweave URLs, track current gateway index via data attributes, and cycle through prioritized gateways on load failures.

In `@components/nft-image/utils/arweave-fallback.ts`:
- Around line 84-97: The element dataset values DS_ORIGINAL and DS_INDEX persist
across reuses causing fallback to continue from a previous asset; modify the
logic around originalSrc/currentSrc (and uses of target.dataset[DS_ORIGINAL],
target.dataset[DS_INDEX], and getGatewayIndexFromUrl) to detect when the
element's src has changed: if target.dataset[DS_ORIGINAL] exists but differs
from currentSrc, reset/clear DS_INDEX and set DS_ORIGINAL to currentSrc so
storedIdx is recomputed for the new asset; ensure currentIdx is then derived
from the fresh storedIdx or getGatewayIndexFromUrl(currentSrc).
