# ADR 0005 — Pagination controls ↔ URL hash bridge

**Date:** 2025-09-02

## Context

We want page navigation to be shareable and restorable via the URL without changing existing app logic.

## Decision

- Add `scripts/init-page-hash.mjs` to delegate clicks on `[data-page]` within `#pagination-top` and `#pagination-bottom`.
- Reflect active page with `aria-current="page"` and `.is-active` class.
- Keep behavior additive; no changes to `script.js` required.

## Consequences

- One extra script tag in `index.html`.
- Existing pagination markup can opt-in by adding `data-page="N"` attributes to clickable elements.
