-Plan: Auto-fill density based on material type
-- Create `client/src/utils/materialDefaults.ts` with density lookup table
-- Convert material field to AutoComplete (dropdown + free text)
+Auto-fill density based on material type:
+- `client/src/utils/materialDefaults.ts` - Density lookup table with fuzzy matching
+- Material field converted to AutoComplete (dropdown suggestions + free text)
 - Fuzzy matching: "PLA Silk" → PLA (1.24 g/cm³)
-- Default diameter: 1.75mm, default density: 1.24 (PLA)
-- Apply to FilamentCreateModal too
-- Do NOT auto-fill on edit page (preserve user customizations)
+- New filaments default to 1.75mm diameter and 1.24 g/cm³ (PLA)
+- Applied to both full create page and FilamentCreateModal
+- Edit page not affected (preserves user customizations)

+See upstream issue: https://github.com/Donkie/Spoolman/issues/671

+Plan:
+- Remove fixed 50% width constraint on QR code
+- Add configurable QR padding setting
+- Allow explicit QR code size control
