width+height attributes or CSS aspect-ratio on the container. No exceptions.next/image, inspect the installed Next.js major. In Next.js 16+, prefer loading="eager" or fetchPriority="high"; use preload only for a single unambiguous LCP candidate (priority is deprecated in 16). Use the API supported by older installed majors rather than copying the newest prop blindly. For plain <img>, use loading="eager" plus fetchpriority="high" on the actual LCP candidate. Everything below the fold: loading="lazy" + decoding="async". Do not preload several viewport-dependent candidates. (Target: LCP ≤ 2.5 s at p75 — the budget lives in governance.)next/image (constrain remotePatterns tightly — SSRF surface, see frontend-security).astro:assets <Image>/<Picture>.<img srcset sizes>; generate AVIF/WebP variants at build time (e.g. vite-imagetools) — don't ship original camera-size JPEGs.sizes must reflect the actual rendered width per breakpoint — a sizes="100vw" default on a 400px card image ships 3× the bytes.fill="currentColor" (icon system rules in design-system).<img src="*.svg"> is fine and cacheable.frontend-security uploads.alt="" when loaded via <img>, aria-hidden="true" when inlined; meaningful → alt text on <img>, or role="img" + <title>/aria-label inline (see a11y).next/font — also removes layout shift via size-adjust fallbacks). Otherwise: self-hosted woff2 only, @font-face with font-display: swap (or optional for non-brand-critical), <link rel="preload"> the critical face, subset to used scripts.@import or third-party CSS CDNs at runtime (render-blocking + privacy). Prefer one variable font over many static weights.<video autoplay muted loop playsinline> or a supported animated image format. Compare real encoded size and browser requirements; avoid GIF when a materially smaller supported format meets the content need.preload="metadata", a real poster, captions <track> required (see a11y), and never autoplay with sound.favicon.ico (legacy), one SVG icon, one 180px apple-touch-icon, web manifest icons. Use the framework's metadata/file conventions rather than hand-written <link> soup.
