+- **Partner packaging assets** — `assets-src/img/partners/`, the retail boxes from eSun, SUNLU and ROSA3D whose spools carry the TIGER TAG RFID badge, in two variants each (a 1024 cut-out with transparent background for compositing, a 2000 studio shot for standalone use). These are the only assets in the project that prove *adoption* rather than describing the product. Masters only — no shipped copy under `assets/` yet, since the use is not decided.

 ## Changed
 
 - **README brought back in line with the app, and given the new artwork.** It was advertising **rack presets**, removed in v2.12.0, and showing `Panda_Feed_Rack_Standard.png`, deleted with them — a dead image on the GitHub page. The presets bullet now describes the actual rack builder, and the image points at the artwork that still exists. The new ecosystem render opens the intro *above* the founder's real-bench photo, which stays: the render shows what the software is, the photo proves someone actually uses it. The TigerPOD line-up banner illustrates its section — nine printed colours say "free STL, print it your colour" better than the sentence under it.

+# Partner packaging — filament makers shipping TigerTag
+
+Photographs of retail boxes from filament manufacturers whose spools carry the **TIGER TAG RFID**
+badge. These are the only assets in the project that prove *adoption* rather than describing the
+product — a render shows what TigerTag is, these show that companies already ship it.
+
+Masters only, at full resolution. **Nothing here is used anywhere yet**, and no optimised copy has
+been produced under `assets/`, because the use is not decided. When one is (an explainer, a partner
+page, a press kit), produce the shipped copy then and mirror its name back here, per the
+`assets-src/` convention.
+
+## Contents
+
+| Brand | Cut-out (transparent) | Studio (grey background) |
+|---|---|---|
+| eSun | `box-esun-cutout.png` — 1024×1024 | `box-esun-studio.jpg` — 2000×2000 |
+| SUNLU | `box-sunlu-cutout.png` — 1024×1024 | `box-sunlu-studio.jpg` — 2000×2000 |
+| ROSA3D | `box-rosa3d-cutout.png` — 1024×1024 | `box-rosa3d-studio.jpg` — 2000×2000 |
+
+Two variants of each shot, both worth keeping:
+
+- **cut-out** — transparent background, drops onto any layout or colour. The one to reach for in an
+  explainer, a lineup, or over a coloured section.
+- **studio** — soft grey backdrop, twice the resolution. The one for a standalone image or print.
+
+The set will grow as more manufacturers adopt the badge; keep the `box-<brand>-<variant>` pattern so
+it stays sortable.
+
+## ⚠️ Before publishing any of these
+
+These photographs show **other companies' trademarks and trade dress** — eSun, SUNLU and ROSA3D
+(whose mark is registered, per the ® on its box). Two separate points:
+
+- **Factual use is normally fine**: showing that a manufacturer's product carries the TigerTag badge
+  is a true statement about a real product, and referring to a brand to describe reality is generally
+  permitted.
+- **Implying endorsement or partnership is not.** A page reading "our partners" over these three
+  logos claims a commercial relationship. If that relationship exists, say so and keep the written
+  permission; if it does not, the wording has to stay factual — "filament makers shipping TigerTag"
+  rather than "our partners".
+
+Ask each manufacturer for written permission before any prominent marketing use. It is usually
+granted readily — a maker who put your badge on their packaging has already chosen to be associated
+with it — and it costs nothing to have on file. Not legal advice; see
+`TigerTag-RFID-Guide/docs/TRADEMARK-FILING.md` for the project's own trademark position.
