Precompute install-audience flag for the hero switcher#366
Merged
Conversation
The home hero's "For humans / For agents" tab was tracked in React state, so every reload snapped back to the default tab and broke the "page is static without layout shift" promise. Model it as a precomputed flag like the other hero flags: - Add `installAudienceFlag` (`'humans' | 'agents'`, cookie key `install-audience`, default `'agents'`) and include it in `rootFlags` so `generatePermutations` covers both variants - Read the flag on the server and publish it via `FlagValues` - New `InstallCommand` client wrapper renders `CommandPromptRoot` with the server value and, on click, writes the cookie + calls `router.refresh()` (optimistic override pattern mirroring `FlagToggle`) Result: the proxy's `precompute(rootFlags)` reads the cookie, rewrites to the matching `[code]`, and SSR renders the correct tab from the start — reloads stay on the user's choice with no client-only state.

Summary
The home hero's "For humans / For agents" tab was held in
useState, so every reload snapped back to the default tab. This PR models the tab as a precomputed flag like the other hero flags.Changes
flags.ts— new `installAudienceFlag` (`'humans' | 'agents'`, cookie key `install-audience`, default `'agents'`), added to `rootFlags` so `generatePermutations` covers both variants (2× permutations, cheap).
