feat(badges): public_access kiosk mode + manager access improvements

- Public (attendee) kiosk: unprinted badges link to /review; printed
  badges show green "Checked in · Nx · First/Last" row (non-clickable)
- Public attendees no longer see Print button (staff-only action)
- Printed badges sort to end of list for public non-trusted users
- Manager access: Print (reprint) and Email Link buttons always visible
  without requiring Edit Mode; main row behavior unchanged
- Empty state wording: context-aware — "Enter your name above to find
  your badge" for public users with no query vs "No badges found" after
  an actual search
- Docs: Epson C3500 fanfold section filled in (was empty placeholder);
  style_href/duplex implementation status corrected in badge templates
  doc; Axonius C3500 layout TODO marked complete

-### Epson — Fan-Fold / Label Printer
+### Epson ColorWorks C3500 — Fan-Fold Label Printer
 
-**Status:** Not yet tested. Section to be filled in after testing.
+**Card stock:** 4" × 6" fan-fold paper label stock
+**Layout code:** `badge_4x6_fanfold`
+**Status:** Configured. First live use: Axonius Adapt DC — June 9, 2026.
 
-Common Epson models used for fan-fold name badge stock: TM-T88 series, C3500, LX series.
-Fan-fold stock is typically 4" × 3" or 4" × 6" paper labels.
+The C3500 is a color inkjet label printer — it prints continuous fan-fold paper stock,
+not individual cards. Badges are separated along the perforation after printing.
+
+#### Physical Setup
+
+- Connect via USB or Ethernet
+- Load 4" × 6" fan-fold stock per Epson instructions
+- The C3500 is single-sided — only the front face prints. Back section is suppressed in CSS.
+- The badge has a lanyard hole punch: 5/8" × 1/8", centered, 1/4" from the top.
+  Most fan-fold stock for badge use includes a pre-punched lanyard slot — verify stock matches.
+
+#### Driver
+
+- Epson ColorWorks C3500 CUPS driver available from epson.com (ColorWorks section)
+- On Linux/CUPS: install the provided PPD and add the printer at `http://localhost:631`
+- Set default paper size to **4" × 6"** in CUPS
+- Print a test page from CUPS before going live
+
+#### Chrome Print Settings (C3500)
+
+| Setting | Value |
+|---|---|
+| Destination | Epson C3500 (CUPS name) |
+| Paper size | 4 × 6 in (set in CUPS driver) |
+| Margins | **None** |
+| Background graphics | On |
+| Pages | 1 (single-sided) |
 
 #### CSS Layout
 
-Fan-fold badges would use a layout sized to the specific label stock.
-A new CSS layout file will need to be created per stock size if not already present.
-Naming convention: `badge_layout_epson_[model]_[size].css`
+The C3500 uses the `badge_4x6_fanfold` layout. CSS file:
+`src/lib/ae_events/badges/css/badge_layout_epson_4x6_fanfold.css`
 
-#### Setup Notes
-
-*(To be filled in after testing — cover: driver source, CUPS setup, paper size, Chrome settings)*
+Created 2026-05-15 for Axonius Adapt DC. Key specs:
+- `badge_front` 4" × 6", portrait orientation
+- `badge_header` max-height 1.5in
+- Lanyard hole: 5/8" × 1/8", centered, 1/4" from top
+- `@page { size: 4in 6in; margin: 0; }` set in the print page dynamically
+- `.badge_back` suppressed in `@media print` (single-sided)
 
 #### Known Behaviors
 
-*(To be filled in after testing)*
+- Same Chrome margin rules apply: **Margins → None** prevents URL/date header clipping
+- Firefox honors `@page { size: 4in 6in }` for PDF proofing — use it to verify layout
+- Fan-fold stock separates along the perforation — no cutting needed, but verify the
+  perforation lands outside the badge content area

 The `duplex` field controls whether the back-of-badge section renders during printing.
 When `false` (single-sided), `badge_back` gets `print:hidden` applied so only the front
 prints. The back section still displays on screen for configuration reference.
