  "summary": "Frontend-only regression testing of OEM logo fallback chain, ecosystem grid curation, marquee ordering, and Palo Alto rendering. Ecosystem grid curation (12 majors), subline, marquee lead order, eyebrow text, '140+ OEM ECOSYSTEM' label, and zero horizontal overflow at 1440 & 390 all VERIFIED FIXED. However, the main user-reported bug ('Palo Alto logo missing / many OEM logos missing') is NOT fixed — the OemLogo 3-stage fallback never advances because Google's favicon CDN returns HTTP 200 with a 16x16 globe placeholder (not a 404), so onError never fires. Screenshot of the Home ecosystem grid proves Palo Alto Networks, Ruckus (and others) render Google's generic globe icon instead of a real logo. 113/140 partner tiles have naturalWidth=0 or <32 (tiny globes).",

Confirmed visually: Palo Alto Networks ecosystem tile (data-testid=ecosystem-tile-palo-alto-networks) renders a globe icon with img.naturalWidth=16, naturalHeight=16, src=https://www.google.com/s2/favicons?domain=paloaltonetworks.com&sz=128. Ruckus tile shows same globe. On /partners (140 tiles), only 27 tiles have naturalWidth>=32; the rest show globes or broken imgs; 0 tiles fall back to monogram.",

    "FIX OemLogo.tsx: Add onLoad handler that advances to stage 1 (DuckDuckGo) when e.currentTarget.naturalWidth <= 16 && naturalHeight <= 16 (Google's default globe size). Google's favicon API never 404s, so onError is insufficient. Example: onLoad={(e) => { if (stage===0 && e.currentTarget.naturalWidth <= 16) setStage(1); }}. Similarly, DuckDuckGo may also return a tiny default — consider a size check on stage 1 as well (threshold ~16px) before accepting.",
    "Consider swapping primary CDN order: DuckDuckGo (icons.duckduckgo.com/ip3/{domain}.ico) often returns the real brand mark for paloaltonetworks.com / ruckuswireless.com where Google only has the globe. Try DuckDuckGo as stage 0.",

The regression (hero, ops console) looks clean visually. The ONLY unresolved issue is the OemLogo fallback not detecting Google's globe placeholder — see action items.

  "rca_of_the_issue": "ROOT CAUSE: Google's favicon service (https://www.google.com/s2/favicons?domain=X&sz=128) is designed to ALWAYS return a 200 OK response — if no favicon is found for the requested domain, it returns a 16x16 default globe PNG rather than a 404. The current OemLogo.tsx fallback chain relies solely on the img onError event to advance from stage 0 (Google) \u2192 stage 1 (DuckDuckGo) \u2192 stage 2 (monogram), but onError is NEVER triggered for a 200 response. Consequently, every domain whose favicon Google doesn't index (paloaltonetworks.com, ruckuswireless.com, and ~110 others) renders the globe placeholder, which is exactly the 'blank/missing logo' the owner reported. REPRODUCTION: open https://aviokan-staging.preview.emergentagent.com/, scroll to 'Technology we work with.' section — Palo Alto Networks tile shows a globe. Inspect the img: naturalWidth=16. MITIGATION: Add onLoad handler to OemLogo.tsx that advances stage when img.naturalWidth<=16 && naturalHeight<=16; or reorder CDNs with DuckDuckGo primary; or maintain a static map of verified OEM logo URLs for the top 20 majors."
