fix(tweet-card): guard against tweets with missing entity arrays

[educlopez]

Problem

smoothui.dev homepage crashed with "This page couldn't load" — client error Uncaught TypeError: r is not iterable (minified).

Real error: entities is not iterable at packages/smoothui/components/tweet-card/index.tsx → enrichTweet(tweet).

react-tweet@3.3.0's getEntities runs for (const entity of tweet.entities.X) with no undefined guard. The Twitter syndication API can omit an entity array (e.g. symbols / user_mentions) for some tweets, which throws during render. The homepage testimonials (WhatTheySay → MediaPlayer → ClientTweetCard → SmoothTweet) call enrichTweet directly with no surrounding error boundary, so the whole page died.

Fix

Normalize tweet.entities into a safeTweet with empty-array defaults before calling enrichTweet. Defensive against any partial or deleted tweet, not just the current offender.

Verification

Reproduced locally in dev (Next 16.2.6): homepage hit the root error boundary. After the fix, homepage loads, 7 tweets render, 0 not-found, no console error. tsc clean for the file.

Summary by CodeRabbit

Bug Fixes

• Fixed tweet card crashes when API responses omit optional data fields
• Improved component resilience by normalizing incoming data to ensure all required structures are properly initialized
• Enhanced overall application stability when rendering tweets from syndication sources with variable data completeness

Walkthrough

SmoothTweet component adds defensive normalization to handle incomplete entity data from the syndication API. Before calling enrichTweet, it now constructs a safeTweet object that guarantees all entity arrays (hashtags, symbols, urls, user_mentions, media) are defined, defaulting to empty arrays when missing.

Changes

Tweet Entity Normalization

Layer / File(s)	Summary
Safe tweet entity arrays wrapper packages/smoothui/components/tweet-card/index.tsx	SmoothTweet now wraps the incoming tweet with a safeTweet that guarantees hashtags, symbols, urls, user_mentions, and media arrays are always defined (defaulting to empty arrays) before passing to enrichTweet, preventing crashes from missing syndication API entity arrays.
