The filter sidebar was missing a lot of specs you can already see in the table. Added eleven of them in one go: CPU PassMark, RAM slots, NVMe interface (Gen5/4/3), M.2 NVMe slots, SATA ports, PSU wattage, and counts for USB-A, USB-C, HDMI, DisplayPort and max displays.
All of these already shipped with the catalog data, so they cost nothing extra to load — you can slice on them right away.
Under the hood
Each new filter reuses the existing range / multi-select components; the NVMe-generation option is derived from the per-slot interface counts by a single shared helper that also feeds the sidebar's counts, so the two can't drift. A few more filters (fanless cooling, OS, dual-LAN) need their columns loaded into the catalog payload first — those are next.
