…equest action Client-side foundation for the lightweight accounts flow: the gated action type union (post_vote / post_subscribe / forecast), a localStorage-backed pending record store shared across trees via useSyncExternalStore (plus the sessionStorage stash for OAuth carry-through), the wire mapping shared by the email and social paths, and the requestEmailLink API client + server action (Turnstile headers, always-204 anti-enumeration contract). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
BottomDrawer wraps Base UI's Drawer (animated enter/exit even when mounted on demand, swipe-down dismiss, max height capped below the navbar). The capture drawer runs the options/input/sent state machine: subscribe opens on checkbox cards with only 'When it resolves' preselected, vote and forecast go straight to email; includes prefilled repeat state, resend cooldown, Google button with action stash, Turnstile, and per-trigger copy in en.json. Registered as the emailCapture modal type. Non-English locales pending translations:generate. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Post votes, question subscriptions, and question-level forecasts now open the capture drawer with the drafted action attached instead of the signup modal. Forecast makers expose buildForecastPayload so the untouched-slider case falls back to a sign-in-only drawer without clearing pending actions. The consumer Predict button opens the maker for visitors (mobile: bottom drawer instead of the fullscreen overlay; one active drawer at a time), and the new NotifyMeCta gives mobile a subscribe entry point. Group/conditional makers and comment/key-factor gates keep the existing signin modal. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Device-local banner under the top chrome while a capture record is pending; tapping it reopens the drawer in recap state with the resend cooldown. The magic-link failure page gains an inline form that requests a fresh link, re-sending the stored gated action when one exists. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The drawer's Google path stashes the pending action in sessionStorage before the redirect; the callback attaches it to the code exchange (backend applies it best-effort per 9e543e5) with a 15-minute staleness guard, and clears the capture record on success.

crypto.randomUUID only exists in secure contexts, so building an OAuth URL crashed the app when the site is accessed over plain http (e.g. LAN device testing against the dev server). getRandomValues has no such restriction. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Mobile capture drawer gets a unified header row: back button or wrapping title inline with the close button at consistent padding (desktop modal unchanged). BinaryCPBar's lg size now draws the SVG at real dimensions instead of a CSS transform, so the layout box matches the visual and the scale-compensation hacks at both call sites are gone. Tighter mobile spacing on consumer question pages (action row, prediction block, notify CTA, drawer paddings) and a consolidated drawer handle gap. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The Share button opens a bottom sheet on mobile (desktop keeps the dropdown): a 2x2 grid of Copy Link / X / Facebook / Embed tiles with pressed-state feedback, toasts on action, and the drawer staying open (Embed hands off to the embed modal). BottomDrawer gains a standard title-plus-close header used by the predict drawer too, and the new DrawerActionButton tile is the building block for future mobile drawers, with share_post_drawer as the reference example. useCopyUrl falls back to execCommand where navigator.clipboard is unavailable (insecure contexts). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Two coherent bundles behind the subscribe_capture_experiment flag: control shows the options step with 'Notify me of updates' copy, test goes straight to the email input under 'Notify me when this resolves' and subscribes to resolution only. Enrollment reuses the anonymous-experiment rails from the autotranslation experiment (middleware evaluation, first-party cookie, same-request header, shared distinct_id) with the variant resolved server-side on the already-dynamic question route so static pages stay static; the root-level drawer falls back to a synchronous cookie read. Exposure registers on surface show, not page load, and capture events carry a captureVariant property. Unenrolled, signed-in, and flag-off all serve the status quo. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Adds es/cs/pt/zh/zh-TW translations for the 62 new keys (email capture
drawer, confirm banner, dead-link recovery, notify CTA, share drawer,
experiment copy). Placeholders and rich-text tags preserved; the
compositional subscribe phrases translated to read grammatically inside
the 'get updates when {a}' sentences.

Refusing to render the tutorial without a user leaves the request itself sitting in modal state, and SimplifiedSignupModal signs a visitor in with a bare setUser while owning its own open state: a stale tutorial would surface the moment a user reappeared, with nothing having asked for it. Clear it when the user goes away. The render guard stays, since the effect runs after paint and would otherwise let a frame of tutorial through. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Let's just only use crypto.getRandomValues instead of fallback?

What if, instead of permanently marking onboarding as complete, we just temporarily hide it during the initial login (see onboardingSuppressedAt)? Then, after 24h, they’ll see the non-intrusive onboarding again.

@aseckin I also recently added a convenient helper for client-side cookies management, could you please integrate it where needed?
Check other places where you might use document.cookie here

Frontend half of Lightweight Accounts P1 (#5045), built against the merged backend (#5052, #5066, #5085, and gated-action support in social auth from 9e543e5).
What this does
When a logged-out visitor takes a consumer action (vote on a question, subscribe to updates, or make a forecast), they get a capture drawer instead of the signup modal: enter an email, receive a magic link, and clicking it verifies the address, signs them in, and applies the action they were trying to take.
Demo

The flow
Mobile share drawer (reusable pattern)
The Share button on question pages now opens a bottom sheet on mobile (desktop keeps the dropdown): a 2x2 grid of Copy Link / X / Facebook / Embed tiles with pressed-state feedback and toasts, the drawer staying open across actions (Embed hands off to the embed modal). This establishes the house pattern for converting desktop interactions into mobile drawers:
BottomDrawerwith thetitleheader +DrawerActionButtontiles, gated at the call site withuseBreakpoint("sm")—share_post_drawer.tsxis the reference example for future drawers.Subscribe-capture A/B experiment
The subscribe flow ships behind a PostHog experiment testing whether the options step earns richer subscriptions or is just friction:
Enrollment reuses the anonymous-experiment infrastructure from #5082: middleware evaluates the flag server-side for eligible anonymous document requests, pins the assignment in a 26-week first-party cookie (plus a same-request header so the first pageview renders correctly), and shares the distinct_id with the autotranslation experiment so one visitor never has two identities. The variant is resolved server-side only on the question route (already dynamic) so static pages stay static.
PostHog setup
subscribe_capture_experiment, variantscontrolandtest, 50/50 split. No targeting conditions needed (the middleware already restricts enrollment to anonymous non-bot visitors).emailSubmittedfiltered totrigger = post_subscribe, relative to exposure.subscribeOptionsContinuedfires only in control and carries theselectedtypes array; test is constant at one type. Also watchcaptureAbandoned(withstep) for where each arm loses people.captureVariantproperty (control/test/none), and bootstrapped flags stamp$feature/subscribe_capture_experimenton every event.Local/staging testing without the flag: pin an arm by setting the cookie
