Episode 3 of The Web Development Podcast dives into the hidden bloat of CSS frameworks. Lucas and Luna break down why a typical Bootstrap 5 setup delivers over 800KB of unused CSS — and how modern alternatives like utility-first Tailwind CSS or CSS Container Queries can slash that to under 10KB. They walk through real-world numbers from a 2025 e-commerce site rebuild, compare the bundle-size impact of popular frameworks, and explain why the web's median page weight has crept past 2.5MB. If you've ever wondered whether your CSS framework is slowing down your users, this episode gives you the data to decide — plus practical tips for auditing your own stylesheet with tools like PurgeCSS and Chrome DevTools coverage reports.

Lucas and Luna unpack a real-world performance bottleneck that silently plagues many React applications: unnecessary re-renders caused by unstable callback references. Using a concrete example from a mid-size e-commerce site, they walk through how useCallback and useMemo work under the hood, when they actually help, and when they make things worse. They also reveal one surprising React profiler reading that showed a 400-millisecond render delay from a single inline arrow function. If you write React code—or review it—this episode will change how you think about component memoization.

Lucas and Luna kick off The Web Development Podcast by dissecting a single real-world failure: a serverless function that ran wild and racked up a $47,000 bill for a 12-person startup. They break down why 'it works on my machine' thinking is dangerous, how cold starts actually work under the hood, and what a proper error budget looks like. Along the way, they preview the show's style — specific numbers, real cases, and a refusal to hand-wave about 'best practices' without showing the trade-offs. No hot takes, no tool-worship. Just two developers talking through the decisions that actually matter when you're shipping to production.
