Two related visibility fixes:
1) Light-mode --acid → #0AC18E (Bitcoin Cash brand primary, from
whybitcoincash.com's palette per user). Direct swap from #088A66
(darkened variant) to the on-brand primary. Applied across chrome /
settings / error / home / approval / messages / bchwallet /
siawallet / screenshot editor. Dark mode's #d6ff3d is unchanged.
2) User-Agent no longer includes 'theseus-navigator/<ver>' or
'Electron/<ver>' tokens. Cloudflare's WAF was returning HTTP 503
'Service Unavailable' to any request carrying those (verified
directly against whybitcoincash.com — same URL, same headers, only
the UA differed; plain Chrome UA got 200, Theseus UA got 503).
Strip both tokens via a stockChromeUA() helper called from
applyAcceptLanguage(), which whenReady already invokes at boot.
Standard practice: Brave, Vivaldi, Slack all do the same.
Verified via CDP: navigator.userAgent now reports
Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36
(KHTML, like Gecko) Chrome/130.0.6723.191 Safari/537.36
— indistinguishable from stock Chrome.
