🚨 Changes in ENV variables

• #3293:
  • Added NEXT_PUBLIC_USERCENTRICS_CONFIG — JSON object with settingsId and/or rulesetId. When set, injects the Usercentrics CMP script and gates third-party analytics, monitoring, and ad services behind user consent.
  • Added NEXT_PUBLIC_USERCENTRICS_DRAFT — set to true to load the unpublished (draft) CMP configuration for previewing consent changes before publishing. Only valid when NEXT_PUBLIC_USERCENTRICS_CONFIG is set.
• #3461:
  • Added NEXT_PUBLIC_STATS_API_REFETCH_INTERVAL — JSON map controlling how often (ms) Stats API resources are refetched in the background (keys: stats:counters, stats:pages_main), e.g. for live-updating average block time. Only valid when NEXT_PUBLIC_STATS_API_HOST is configured.
• #3476:
  • Added NEXT_PUBLIC_PRO_API_SUPPORTED (boolean) — controls whether the PRO API tab appears in the API docs. Automatically set at container startup based on the chain's membership in the Blockscout Pro API; can be manually overridden.
  • Extended NEXT_PUBLIC_API_DOCS_TABS with a new pro_api tab ID.
• #3516:
  • Changed the default value of NEXT_PUBLIC_OG_ENHANCED_DATA_ENABLED from false to true.
• #3520:
  • Extended NEXT_PUBLIC_VIEWS_TX_HIDDEN_FIELDS with four new field IDs — L1_gas_used, L1_gas_price, L1_fee, L1_fee_scalar — to allow hiding L1 fee datapoints individually on the transaction details page.
• #3531:
  • Removed NEXT_PUBLIC_HAS_MUD_FRAMEWORK (MUD framework feature removed); moved to deprecated ENVs.
