One word everywhere: ReplyPier in UI copy, package and image names, the replypier.site domains (app/api/docs/help), REPLYPIER_* settings and the --rp-* design tokens. - public widget API is window.ReplyPier with replypierId / replypierBaseUrl / replypierConfig / replypierToken, loader at webclient/replypier.min.js; both bundles rebuilt from source - NOTICE, llms.txt, CONTRIBUTING, HELP_CENTER_INFRA and the demo runtime config rewritten; the demo config ships no third-party keys - migration adds the ReplyPier managed model value to the AI model enum - local compose project, database, role, volume and Docker network carry the same name

PDFs we will not index, and why.
|
|
|
|
Bytes don't bound the work: a small file can hold thousands of pages, and a
|
|
PDF is read page by page - every page's text embedded, and a scanned one
|
|
OCR'd at a second or more a page. So the page count is limited too, checked
|
|
before any of it is read.
