From 0da7498ad71a7ba9e74a4363a73ec22b25628c62 Mon Sep 17 00:00:00 2001 From: Stephen Adamson Date: Thu, 4 Jun 2026 01:06:33 +0100 Subject: [PATCH] feat(images): multi-format portfolio pipeline (AVIF/WebP/JPEG/JXL) Backend now stores AVIF, WebP, JPEG, and optional JXL variants for both full-size and thumbnail images. Database schema extended with 7 new columns. Image validation supports AVIF and JXL magic bytes. Comprehensive test coverage for all format URL fields and magic byte detection. Legacy single-URL images remain backward-compatible.
