Keep lookup keys and display shapes distinct

Draw the shape; retain its key

import { radicalForm } from "@johnmorrisdotca/bushu";
import { radicalName, radicalNameForShape, radicalNameEntry } from "@johnmorrisdotca/bushu/names";
console.log(radicalForm("汁"),radicalName("汁"),radicalNameForShape("氵"));
console.log(radicalNameEntry("邦")?.name,radicalNameEntry("阡")?.name);

氵 さんずい さんずい
おおざと こざとへん

RADKFILE uses stand-in keys such as 汁 for 氵. Display radicalForm(key) while keeping the key in your lookup state. Both 邦 and 阡 display 阝; they have different kanji memberships and different names. Key-based lookup preserves that distinction. Shape-name lookup deliberately chooses the first matching school name for an ambiguous shape.

Handle unnamed components

The names table covers school radical names, not every component used by the search index. radicalName and radicalNameEntry return null when the table has no name. Show the native form or a neutral fallback rather than inventing a reading. Position and Kangxi number within a known entry may also be null.
