fix(interfaces): always-light public surfaces (chat, resume, file shares, unsubscribe, invite) with emcn components

[TheodoreSpeaks]

Summary

No API endpoints changed — this is UI-only, across the public page routes:

/chat/:identifier (deployed chat)

• Rendered dark for everyone: the overlay hard-coded a dark class and used the retired static-dark --landing-* tokens, overriding the ThemeProvider's forced-light. Now pins light + platform tokens — never follows the visitor theme
• Header uses the platform inline SimWordmark (was the white sim-landing.svg asset)
• Hand-rolled composer buttons, scroll-to-bottom, copy, error-state CTA → emcn Button; markdown renderer aligned to platform Chat conventions (token-based, light code blocks)

/resume/:workflowId/:executionId (human-in-the-loop resume)

• Dropped the redundant landing marketing Navbar (the interfaces shell already provides the light logo chrome — nav was doubled)
• All inline style={{}} converted to Tailwind + platform tokens; legacy @/components/ui Select → ChipSelect; form controls → ChipInput/ChipTextarea with proper error wiring

/f/:token (public file shares)

• Auth gates (password / email OTP / SSO) were the old dark landing chrome (hard dark class, dark AuthBackground, marketing Navbar) — rebuilt on the light LogoShell + SupportFooter frame, same as the chat gates
• File view forced light; theme-dependent double logo → SimWordmark

/unsubscribe + /invite/:id

• Fixed invisible text: headings used --landing-text (#ececec) inside the light AuthShell — white-on-white. Swapped to platform tokens
• Legacy white-on-white AUTH_SUBMIT_BTN CTAs → AuthSubmitButton (same emcn Chip as login/signup); secondary actions as bordered neutral chips

Cross-cutting

• ThemeProvider forced-light list now includes /f/ and /unsubscribe
• Chat SSO gate (ee/sso) CTAs migrated off the legacy class too
• Deleted dead code: AuthBackground + auth-background-svg (zero consumers) and the AUTH_SUBMIT_BTN/AUTH_PRIMARY_CTA_BASE class strings

Type of Change

• Bug fix

Testing

Verified in the browser against a local deployed chat, a real /f/:token share (view + password gate), /unsubscribe, and the resume page — all render light with readable text regardless of system theme. bun run lint:check, bun run type-check, bun run check:api-validation:strict, and the interfaces vitest suite pass. No --landing-* tokens or dark: variants remain on these surfaces.

PR Summary

Low Risk
Visual and component-library refactors across chat, resume, and auth shells; resume submission logic is unchanged aside from equivalent form controls.

Overview
Deployed chat and voice overlays now force light and use platform tokens (--bg, --text-primary, --surface-*) instead of a hard-coded dark class and retired --landing-* variables, so they stay light even when the visitor’s theme differs.

Chat UI is aligned to the design system: composer and message actions use emcn Button variants, the header uses SimWordmark, and markdown/code blocks use token-based styling (dashed links, light surfaces) rather than gray/dark Tailwind pairs.

Paused execution (resume) drops the extra landing Navbar and inline styles in favor of layout inside the interfaces shell; form fields move to ChipInput / ChipSelect / ChipTextarea with validation error wiring on editable fields.

Auth-adjacent surfaces remove the decorative AuthBackground stack; public file gates use LogoShell, and password/OTP/SSO/invite/unsubscribe flows standardize on AuthSubmitButton (and secondary Chip where needed) instead of AUTH_SUBMIT_BTN class strings.

ThemeProvider extends forced-light routing to /f/ and /unsubscribe.

Greptile Summary

This PR fixes a bug where the deployed chat overlay was hardcoded with a dark CSS class and --landing-* static-dark tokens, overriding the ThemeProvider's forced-light on /chat and /resume for all visitors. The fix pins the overlay to light and migrates every --landing-* token reference to platform tokens (--bg, --text-primary, --surface-*, etc.).

• Chat/voice-interface/resume overlay fix: replaced dark class and --landing-* tokens with light class and platform tokens across chat.tsx, voice-interface.tsx, and all child components; also swaps the white sim-landing.svg wordmark for SimWordmark (inline SVG, var(--text-body) fill).
• Auth surface cleanup: deletes the dark AuthBackground/AuthBackgroundSVG components, deprecates AUTH_SUBMIT_BTN/AUTH_PRIMARY_CTA_BASE class strings in favor of the canonical AuthSubmitButton Chip component, and updates all auth-adjacent pages (/f/, /invite, /unsubscribe, SSO) to use platform tokens through the existing LogoShell/AuthShell wrappers (both already pin light).
• Resume page refactor: replaces legacy @/components/ui Select/Input/Textarea and the removed Navbar with emcn ChipSelect/ChipInput/ChipTextarea, and converts all inline style={{}} to Tailwind utility classes.

Confidence Score: 5/5

Safe to merge — the change corrects a real rendering bug with no functional regressions in the changed paths.

The hard-coded dark class removal is a direct, well-scoped fix whose token migration is consistent across all 26 files. The deleted AuthBackground/AUTH_SUBMIT_BTN/AUTH_PRIMARY_CTA_BASE artifacts have been replaced by canonical AuthShell/LogoShell/AuthSubmitButton components that already pin light at the component level. No API contracts, data models, or server routes were modified.

No files require special attention.

apps/sim/app/(interfaces)/resume/[workflowId]/[executionId]/resume-page-client.tsx	Large refactor: drops legacy Select/Input/Textarea/Navbar; uses emcn ChipSelect/ChipInput/ChipTextarea; converts all inline style={} to Tailwind classes.
apps/sim/app/_shell/providers/theme-provider.tsx	Adds /f/ and /unsubscribe to the forced-light-mode path list, belt-and-suspenders for pages whose shells already pin light at the component level.
