+--
+-- Sources:
+--   7800R4-36D2-LC: arista.com official product CDN (15KB PNG). Arista uses
+--     `7800R3A-36P-LC-150-v2.png` as the canonical LC image for ALL 7800R4
+--     line card variants on their product page; no dedicated 36D2-LC image
+--     exists (7800R4-36D2-LC announced Oct 2025, not yet in reseller catalogs).
+--     Same official CDN origin as other Arista images in this project.
+--   8101-32FH: router-switch.com Magento CDN (57KB JPEG), cisco-8101-32fh.jpg.
+--     Cisco.com returns 403 for direct asset fetches on 8000-series images.
+--     NetworkTigers does not carry the Cisco 8000 series (0 search results).
+--     router-switch.com (an authorised Cisco reseller/reseller) hosts per-SKU
+--     product images using the naming convention c/i/cisco-{model}.jpg.
+--   8111-32EH: stack-systems.com Magento CDN (9.6KB JPEG). Cisco 8000-series
+--     images are not publicly accessible on Cisco.com or NetworkTigers. The
+--     stack-systems.com image is the only available verified CDN image for this
+--     model across authorised resellers (Magento cache, confirmed image/jpeg,
+--     verified HTTP 200).
+--   C9300X-24Y: networktigers.com Shopify CDN (64KB JPEG), cisco-C9300X-24Y-A.
+--     Standard NetworkTigers per-SKU CDN pattern used throughout this project.
+--   C9500-48Y4C: networktigers.com Shopify CDN (50KB JPEG), C9500-48Y4C-E with
+--     UUID suffix (Shopify multi-image dedup pattern).
+--   N9K-C93108TC-FX3P: networktigers.com Shopify CDN (78KB JPEG), full-res
+--     (not progressive 463x version). Same Shopify CDN pattern as other Nexus
+--     9000-series images in previous migrations.
+--   PTX10001-36MR: juniper.net official image library Azure CDN (112KB JPEG).
+--     Juniper maintains a dedicated per-model image library at
+--     juniper.net/content/dam/www/assets/images/us/en/image-library/ptx-series/.
+--   PTX10004: juniper.net official image library Azure CDN (138KB JPEG),
+--     lbox-ptx10004-front.jpg. The full-res ptx10004-front-high.jpg is 1.26MB
+--     (impractical for web display); the lbox variant provides equivalent
+--     front-panel clarity at 138KB.
