// --- Auto-popup storage helpers ------------------------------------------- |
| 405 |
// |
| 406 |
// Two independent pieces of state decide whether the auto-popup can show: |
| 407 |
// |
| 408 |
// 1. A per-TAB flag (sessionStorage, key below) - "has THIS tab already auto- |
| 409 |
// shown the popup?". sessionStorage is naturally scoped to one tab and |
| 410 |
// survives reloads within it, but a brand new tab/window always starts |
| 411 |
// fresh - exactly the "once per tab" semantics we want. |
| 412 |
// |
| 413 |
// 2. A cross-TAB counter with a 24h rolling window (localStorage, key below) |
| 414 |
// - "how many times has ANY tab shown the popup in the current 24h |
| 415 |
// period?". localStorage is shared by every same-origin tab, so this is |
| 416 |
// the single source of truth for the display limit. |
| 417 |
// |
| 418 |
// Concurrency note: localStorage has no built-in atomic read-modify-write, |
| 419 |
// so two tabs could both read count=2 (limit 3) before either writes back |
| 420 |
// 3, and each would believe it won the last slot - a classic |
| 421 |
// check-then-act race. Where the browser supports the Web Locks API |
| 422 |
// (https://developer.mozilla.org/en-US/docs/Web/API/Web_Locks_API - current |
| 423 |
// Chrome/Edge/Firefox/Safari), consumeGlobalPopupSlot() uses it to make the |
| 424 |
// read-check-increment sequence a genuine cross-tab critical section, which |
| 425 |
// closes this race entirely. On older browsers without Web Locks, the same |
| 426 |
// function falls back to a best-effort read-then-write - there remains a |
| 427 |
// small theoretical window where two timers firing at the exact same |
| 428 |
// instant could both succeed, but this is a client-side popup nicety, not |
| 429 |
// a security or billing boundary, so the practical risk (occasionally |
| 430 |
// showing one extra popup out of many tabs closing in the same millisecond) |
| 431 |
// is an acceptable trade-off for staying purely client-side. |
| 432 |
|
