Three issues caught by the code review of scripts/gen-icons.mjs:
(1) Missing source SVG validation. Spec requires the script "refuses
to run if any source SVG is missing." Added an existsSync guard at the
top of main() that throws a targeted message rather than letting sharp
fail with a raw ENOENT.
(2) Summary table missing byte sizes. Spec says the summary prints
"each output, its size in pixels, its file size in bytes." trace() now
captures statSync().size; the printout has a size column with
human-readable formatting and a total at the end.
(3) writeMaskablePng's intermediate buffer used .png() without the
compressionLevel/palette options that every other render uses. Zero
functional impact (the buffer is only piped into composite, never
written to disk) but inconsistent and misleading. Aligned with the
rest of the script.
README: replaced 'git add -A' with explicit directory paths matching
the project's convention — the generator writes to a fixed set of
three directories and shouldn't accidentally stage unrelated
working-tree changes during a regen.
Plan updated to match the corrected code so Task 3's source-of-truth
stays consistent.
