Review a diff for performance cost and lifecycle fragility — before opening a PR, when a change touches scripts.js, ak.js, head.html, images, fonts or dependencies, or when a block wants to hook into core page load for "speed". Analyses the change against the load lifecycle; does not measure.
Normalise a supplied SVG into an icon this project can use — before one lands in img/icons/, when an existing icon renders blank or ignores the colour scheme, or after a designer re-export. Rewrites the mechanical parts in place and reports the judgement calls instead of guessing at them.
