yuanzonghao ae3dd17e6b feat(web): add player name, freeform input, and unified settings modal
- Player name: stored in localStorage, injected into Architect/Writer/InsertBeat
  prompts so NPCs address the player by name, displayed in dialogue UI
- Freeform input: compact button at choice nodes expands to text input, LLM
  classifier routes to insert-beat (interactive NPC response) or change-scene
- SettingsModal: unified panel merging player name, voice toggle (with
  collapsible TTS key section), replacing the old TtsKeyModal
- Insert-beat upgrade: prompt now requires NPC reaction when characters are
  present, shared by both freeform and Vision paths
- IME guard: isComposing check on freeform input to prevent CJK mid-composition
  submission

// Privacy-first analytics. Sends only content-free, categorical events to
// Umami, and only when the tracker script is actually present (gated by the
// NEXT_PUBLIC_UMAMI_* env vars in components/Analytics.tsx). With no script
// loaded — local dev, forks, a non-matching data-domains host, or a visitor
// with Do Not Track — `window.umami` is undefined and every call here is a
// silent no-op: zero runtime impact, no errors.
//
// RULE: never pass free text (player prompts, custom world/style guides,
// uploaded images, vision output) or any per-user identifier. Only enums,
// indices, counts and booleans — that is what keeps these events as
// privacy-friendly as the cookieless page-view baseline.
import type { ArtStyle, Gender, Pacing, PlotStyle } from "./options";
declare global {
interface Window {
umami?: {
track: (event: string, data?: Record<string, unknown>) => void;
};
}
}
// Per-event payload schema. Fixing each event's allowed fields turns the RULE
// above into a compile-time guarantee: an event simply has no slot for a prompt,
// world/style guide or vision string, so free text can't be attached by mistake
// (a bare `Record<string, string>` would happily accept it). Every field is a
// literal union (shared with the selector UI via ./options), index, count or
// boolean — never a bare `string`. `never` marks events that carry no payload.
