feat(emails): transactional email primitives and redesigned templates (#2741) * feat(emails): transactional email primitives and redesigned templates Build the shared transactional layout (header bar + state pill, eyebrow, title/lede, callout, key-value table, code block, steps, actions, signature, footer outside the card) and port every template that used the old layout: monitor alert, private-location alert, status report + maintenance, inactivity warning + paused, SSO disabled, team invitation, page subscription, status-page magic link. - monitor alert renders the React template again instead of the hotfix HTML string; subject follows " — " - inactivity mails render through React too, with monitor count and workspace slug; hotfix/ is removed - status report escapes raw HTML in the markdown message - dates are UTC with an explicit suffix, day-only dates drop it - delete the unscheduled duplicate follow-up and team-invite web routes - lowercase "openstatus" in subjects, senders and email copy Co-Authored-By: Claude Fable 5.1 * fix(emails): address review findings - brand link on one-time emails (verify, magic link) points at the page origin so a mail scanner cannot consume the token; logo is no longer an unnamed link - darken faint/muted text to 4.5:1 contrast - pass the HTTP method only for HTTP monitors - private-location monitor count ignores paused and deleted monitors - status report escaping keeps autolinks and author-written entities - no empty eyebrow, truthy workspace-name fallback, scope-neutral subscription copy, SSO described as a paid add-on - page subscriber verification uses the shared notifications@ sender Co-Authored-By: Claude Fable 5.1 * fix(emails): safe status report markdown, one subscription email - status report messages render through our own marked renderer: raw HTML is escaped in the renderer, link and image URLs are attribute-escaped and must be http(s)/mailto. react-email's Markdown wrote hrefs unescaped, so injected an attribute, and javascript: links passed through - the public v1 subscribe route sends the redesigned PageSubscriptionEmail, same as the status page form; subscribe.tsx is removed - delivery.enabled() indirection so send paths are testable Co-Authored-By: Claude Fable 5.1 * chore: record marked in deno.lock Co-Authored-By: Claude Fable 5.1 * refactor(emails): gate every sender on delivery.enabled() Co-Authored-By: Claude Fable 5.1 * wip: * ci: apply automated fixes * wip: * fix: list md style * fix(emails): table width, impacts as of the update, drop empty value cell Co-Authored-By: Claude Fable 5.1 * refactor(emails): drop retry from monitor alert, fix empty workspace name in invitation Co-Authored-By: Claude Fable 5.1 * fix: move package to catalog * fix: --------- Co-authored-by: Claude Fable 5.1 Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com>
