    An Embed Is Not a Component

    A third-party embed is a second website loaded into yours, with its own dependency tree, its own budget, and no build-time guarantees at all.Web Performance · Static Architecture · Web Architecture    A pristine brass clockwork engine in a fog-filled steampunk vault, an enormous foreign apparatus of mismatched iron bolted crudely onto its flank, thick ribbed cables running from it out into total darkness beyond the frame, the engine glowing neon teal while the parasite machine pulses a sickly amber

    Your Fallback Font Is Doing the Layout

    font-display: swap does not fix font loading. It converts invisible text into a layout shift, and the fallback metrics decide how bad that shift gets.Web Performance · Static Architecture    A colossal brass typesetting frame in a fog-filled steampunk hall, a ghostly translucent neon-teal slug of placeholder metal type holding open an exact gap in a tall column of copper letterforms, a heavier brass replacement letter suspended on chains directly above it, the entire column below poised to lurch downward

    Preload Is a Zero-Sum Game

    A preload does not create bandwidth. It reorders a queue. Everything you promote pushes something else down, and usually that something is your LCP.Web Performance · Static Architecture · Web Architecture    A colossal brass balance scale inside a fog-filled steampunk engine hall, glowing neon-teal cargo crates stacked high on one pan while the opposite pan rises into darkness, copper chains straining under a single fixed weight that can never be added to, only moved

    Cache-Control Is the Config File You Never Wrote

    Your static site is fast in the lab and mediocre on repeat visits. The fix is not a bundler flag. It is two tiers of cache headers, written down.Web Performance · Static Architecture · Web Architecture    A colossal brass sorting engine in a fog-filled vault, clockwork arms stamping glowing hourglass seals onto passing crates as they split into two lanes — one lane sealed in amber and locked away for a century, the other flashing teal and released within seconds, dark steampunk machinery lit by neon circuitry

    You Don't Need a Form Library

    HTML5 has had client-side validation for over a decade. :user-invalid, setCustomValidity(), and the novalidate pattern cover 95% of what React Hook Form does — and the last CSS gap closed in late 2023.Signal vs Noise · Developer Experience (DX) · Web Performance · Static Architecture    A self-contained steampunk brass inspection machine in a dimly-lit workshop, scrolls of data feeding through an internal mechanism of gears and calibrated gauges that stamps each scroll with an emerald verification seal, all mechanisms internal with no external wires or cables leading outside the machine, amber furnace glow from within, reflective wet stone floor with faintly glowing circuit-pattern grouting in teal and amber, atmospheric purple fog filling the background, cinematic shallow depth of field, moody editorial composition, no text, no people

    Lighthouse CI Without a SaaS

    Performance-monitoring SaaS sells you a wrapper around a tool you already have. GitHub Actions and Lighthouse CI fail the build on regressions for free.DevOps · Web Performance · Automation · Signal vs Noise    A towering brass and copper steampunk lighthouse on a dark rocky promontory at night, its rotating beam a focused shaft of teal neon sweeping across a procession of small mechanical clockwork ships approaching through purple fog, a heavy gear-driven gate-arm lowered across the narrow channel to block one ship while a glowing green signal lamp waves another through, the lighthouse self-contained and powered by its own visible furnace of amber gears with no cables or wires running off to the distant dim shore, reflective wet stone and black water below catching the neon reflections, cinematic shallow depth of field, moody editorial composition, no text, no people

    Stop Loading Google Fonts

    Google Fonts is a tracker that happens to also serve fonts. Self-hosting is faster, more private, and a one-afternoon migration in 2026.Signal vs Noise · Web Performance · Developer Experience (DX)    A vast dark steampunk type foundry at night, a single self-contained brass workshop in the foreground glowing with its own amber furnace and rows of movable-type cases being assembled into a clockwork printing press, severed copper data pipelines hanging loose where they used to stretch out toward a distant cathedral-sized brass font factory receding into atmospheric purple fog, the distant factory now dim and unplugged, the local workshop's furnace humming and casting warm reflections across a reflective wet stone floor with circuit-pattern grouting glowing faintly teal and amber, cinematic shallow depth of field, moody editorial composition, no text, no people

    Why I Deleted Google Analytics

    Google Analytics is slow, GDPR-hostile, undercounted by ad blockers, and answering questions you mostly aren't asking. Here's why I removed it from every site I run, and what I use instead.Signal vs Noise · Web Performance · Developer Experience (DX)    A vast dark steampunk surveillance chamber at night, towering brass observation racks holding hundreds of glass camera-eye lenses receding into atmospheric purple fog, most of the lenses now dim and dark with only a few still flickering faint teal; in the foreground a single solid copper workbench under a fading amber lamp where a heavy brass lever has been pulled all the way down to the OFF position, severed copper data cables hanging loose and unplugged from a tarnished switchboard, a small pile of inert glass eyes set aside beside the lever, reflective wet stone floor with circuit-pattern grouting glowing only faintly amber, cinematic shallow depth of field, moody editorial composition, no text, no people

    The Dependency-Count Audit: Every Package Is a Bet, Not a Free Tool

    Most JS projects have never had their dependency list audited line by line. Doing it once — with a real method instead of vibes — usually halves the count and exposes which packages were doing nothing in the first place.Node.js · Developer Experience (DX) · Web Performance · Signal vs Noise    A vast dark steampunk warehouse filled with rows of towering brass shelving units, each shelf holding hundreds of glowing glass jars connected by tangled copper wiring; in the foreground a single workbench under a hanging amber lamp where a brass-handled magnifying lens hovers over an open ledger, with several jars set aside in a small crate marked for removal, the rest of the warehouse fading into atmospheric fog and neon teal accent lighting along the floor tracks, cinematic shallow depth of field, moody editorial composition, no text, no people

    Code Highlighting at Build Time: Shiki vs Prism and the Death of Runtime Tokenizers

    Shipping a tokenizer to the browser to color code blocks made sense in 2014. It doesn't now. Build-time highlighting is faster, cheaper, and produces better-looking output — and the tradeoffs are smaller than you think.Developer Experience (DX) · Static Architecture · Web Performance · Web Architecture    A vast steampunk type foundry with two opposing chambers — on the left, blocks of code being cast in glowing molten brass at a single calm forge with neon teal flames, finished pages stacked in orderly piles; on the right, a chaotic backroom of frantic clockwork typesetters scrambling to assemble identical pages by hand under harsh amber gaslight, brass gears and copper pipes throughout, atmospheric fog, dark industrial lighting, no text, no people

    Dark Mode Without the Flash

    The white-flash-on-load that ruins half the dark-mode implementations on the web is preventable in about twelve lines of code. CSS variables, a render-blocking script, and one localStorage read — that's the whole trick.Static Architecture · Web Performance · Developer Experience (DX) · Signal vs Noise    A vast brass observatory hall plunged in darkness, with a single mechanical lens flipping a glowing teal day-sigil to a deep purple night-sigil mid-rotation, copper pipework channeling the change instantly across rows of identical static windows, no flicker between them, dark steampunk theme engine

    OpenGraph Images at Build Time: Why Static Sites Win Social Cards

    Generating social card images on demand from a serverless function feels modern. It's also slow, expensive, and fragile. Static sites can pre-render every OG image at build time, cache it forever, and never pay for it again.Next.js · Static Architecture · Web Performance    A vast brass darkroom filled with framed glowing rectangles being stamped into existence by clockwork arms, neon copper light pouring through translucent stencils, dark steampunk image foundry

    Your Lighthouse Score Is a Lie

    A perfect 100 in Lighthouse means your test environment is fast. It says almost nothing about whether real users on real networks are having a fast experience.Signal vs Noise · Web Performance · Web Architecture    A shattered speedometer pinned at 100, surrounded by floating performance metric icons on a dark purple background
