feat(share): sharing-visibility foundation (PR 1)

[tsahimatsliah]

Foundation for the sharing-visibility initiative — a reusable share affordance + flags. Behind flags; share_copy_icon default off means no user-visible change vs main.

Part of the multi-PR sharing-visibility initiative (Storybook-first, one PR per surface). Full plan tracked separately.

Highlights

• ShareActions primitive (icon/inline; desktop popover, mobile native share) + Storybook story
• feature_sharing_visibility master kill-switch + useSharingVisibility gate
• core copy-icon swap (LinkIcon→CopyIcon) gated behind share_copy_icon (default off) via useShareCopyIcon
• new share-surface Origin values

🧭 Task context (auto-maintained by /fresh)

• Goal: Increase sharing visibility across daily.dev — add copy-link/share affordances on ~26 surfaces + an onboarding invite→Plus step, delivered as one PR per topic.
• Branch: claude/website-sharing-visibility-be6b32 → main
• Updated: 2026-07-21

Current focus: PR 1 (Foundation) is complete. Next up is PR 2 (feed-card copy-icon + hover share-out), Storybook-first.

Decisions (and why):

• Storybook-first for every PR — build/iterate the component + story, get look-and-feel sign-off, THEN wire into surfaces (saves credits, faster iteration).
• Per-topic GrowthBook flags + master kill-switch feature_sharing_visibility (all default false).
• Core copy-icon swap (LinkIcon→CopyIcon) gated behind its OWN flag share_copy_icon (default off) — changing a core high-traffic icon must ramp independently to protect metrics; flag-off == main.
• Reuse existing infra: useShareOrCopyLink, SocialShareList, getShareLink/ShareProvider, useGetShortUrl, Radix Popover.
• Research: OG meta is the feat: turn links in comments to anchor elements #1 lever (link networks ignore URL params); TikTok dropped (no web intent); Slack has no share-intent URL (needs unfurl/OG or Slack app).

Key files:

• packages/shared/src/components/share/ShareActions.tsx — reusable primitive (icon/inline; desktop popover + mobile native share; onShare(provider) callback)
• packages/shared/src/hooks/useSharingVisibility.ts — master gate; useShareCopyIcon.ts — icon-swap gate
• packages/shared/src/lib/featureManagement.ts — feature_sharing_visibility, share_copy_icon
• packages/shared/src/lib/log.ts — new share Origins
• packages/storybook/stories/components/ShareActions.stories.tsx — Icon/IconOpenOnHover/Inline stories
• Gated icon swap: ShareMobile.tsx, cards/common/ActionButtons.v2.tsx, post/brief/BriefPostHeaderActions.tsx
• Full plan (not in repo): ~/.claude/plans/okay-we-have-an-cheeky-pearl.md

Done:

• PR 1 foundation: ShareActions + story, both flags + gates, gated copy-icon swap on 3 surfaces, new Origins.
• Verified: strict typecheck, lint, tests (ShareActions 3/3 + card/brief 30/30), Storybook renders (localhost:6006).

Next:

• PR 2 — feed-card: swap copy action to CopyIcon (flag) + hover-reveal share-out popover (Slack/WhatsApp/socials); mirror on comments (copy-permalink primary). Build story first.

Gotchas:

• Two architectural splits to respect: engagement bar V1/V2 (useEngagementBarV2, .tsx↔.v2.tsx) and post redesign Focus Card (usePostRedesign).
• No OG-image library — dynamic images = screenshot of Next pages under pages/image-generator/* (id="screenshot_wrapper").
• Storybook story decorators need QueryClient + AuthContext + LogContext + mock ['shortUrl'] (useGetShortUrl reads AuthContext).
• Node here is 24.17 vs repo 24.18 (harmless engine warning); deps needed pnpm install in this worktree.
• ShareActions primitive itself uses CopyIcon unconditionally — fine, it's net-new UI wired only behind per-surface flags later. Only swaps on EXISTING surfaces are gated.
