=== 1. Core Module Optimization ([[Module:InfoboxImage/sandbox]]) ===
* '''File Namespace Caching (Performance):''' The current production code queries and rebuilds the file namespace aliases table via `mw.site.namespaces[6]` twice on ''every single invocation'' (once inside `IsPlaceholder` and again in the main function body). On long pages or transclusions, this creates unnecessary overhead. The proposed version builds this namespace cache list exactly once at the top-level scope during the initial module load.
* '''Redundant Code & Asserts Cleanup:''' Removed several `assert(image ~= nil)` checks right after `mw.ustring.gsub`. In the Scribunto environment, these standard string operations never return `nil` when provided with valid string inputs, meaning these assertions were purely redundant and polluting the code logic.
* '''Namespace Stripping Helper:''' Unified the file prefix stripping logic into a streamlined internal helper function `stripNamespace`, reducing code duplication between functions.
