Greptile Summary

This PR adds Japan Post Bank to the brand catalog with two SVG assets (default.svg and wordmark.svg) and a new entry in icons.json. The brand colour (#009900) is correctly applied to all paths in both files.

• Both SVG files carry explicit width and height attributes set to the raw artwork dimensions (1548×1087 and 1548×139), which will render at full pixel size in any <img> context without a CSS override — all other icons in the library either omit these or use small normalised values.
• Both SVGs are missing the <title> element that every other icon in the repository includes for accessibility and tooling compatibility.
• The icons.json entry uses a tab character to indent the opening brace instead of the two-space convention used throughout the file (previously flagged).

Confidence Score: 4/5

Safe to merge once the hardcoded large width/height attributes are resolved; the icon data and colours are otherwise correct.

The SVG files embed their intrinsic dimensions at 1548 pixels wide, which will break rendering wherever the icons are consumed as image elements without an explicit size override. Every other icon in the library avoids this by using small or omitted dimensions. This is a present rendering defect on the changed files, not a speculative concern.

Both public/icons/japan-post-bank/default.svg and public/icons/japan-post-bank/wordmark.svg need their width/height attributes corrected before the icons will render predictably across the consuming UI.

Important Files Changed

Filename	Overview
public/icons/japan-post-bank/default.svg	New icon SVG; both paths have correct brand colour (#009900), but the file carries hardcoded width="1548" height="1087" and is missing a <title> element — deviating from established library conventions.
public/icons/japan-post-bank/wordmark.svg	New wordmark SVG; all three paths use fill="#009900" correctly, but shares the same large intrinsic dimensions (1548×139) and missing <title> issues as default.svg.
src/data/icons.json	Japan Post Bank entry added with correct slug, hex, category, URL, and license; the opening brace is indented with a tab instead of two spaces (already flagged in a prior review thread).
