Add explicit return types to the helper functions.

Line 5 and Line 9 omit return type annotations. Add them to meet the TypeScript guideline.

Proposed fix

-const bare = (unicode: string) => unicode.replace(/️/g, '');
+const bare = (unicode: string): string => unicode.replace(/️/g, '');

-const buildAliasIndex = () => {
+const buildAliasIndex = (): Record<string, string[]> => {

As per coding guidelines, add explicit type annotations to function parameters and return types.

156-157: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Use an escape sequence for the variation selector.

Line 157 contains a literal U+FE0F inside the regex. The character is invisible in the source. An editor, a copy-paste, or a formatter can remove it without any visible change, and bare() then stops stripping the variation selector. The legacy fold at line 174 depends on bare(), so the failure is silent.

Use the escape sequence instead.

♻️ Proposed change

-const bare = unicode => unicode.replace(/️/g, '');
+const bare = unicode => unicode.replace(/\uFE0F/g, '');

40-43: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Add a test for the legacy fallback path.

This test covers the alias path in shortnameToUnicodeMap. The change in app/lib/hooks/useShortnameToUnicode/index.tsx lines 7-8 also added a fallback to legacyShortnameToUnicodeMap. That branch has no coverage here. The legacy map exists to keep stored reactions rendering, so a regression in that branch is silent.

Add a case that resolves only through the legacy map.

💚 Proposed test

 // emojibase emits the emoji presentation sequence, hence the trailing U+FE0F.
 test('render alias shortnames', () => {
 	const unicodeEmoji = renderShortnameToUnicode(':water_wave::thumbs_up::red_heart:');
 	expect(unicodeEmoji).toBe('🌊👍\uFE0F❤\uFE0F');
 });
+
+// These names are no longer listed by emojibase, but stored reactions still use them.
+test('render legacy shortnames', () => {
+	const unicodeEmoji = renderShortnameToUnicode(':iphone::large_blue_circle:');
+	expect(unicodeEmoji).toBe('📱🔵');
+});
