Sastra — PWA Starter Kit
========================

These files make your Sastra visual novel installable and playable offline.
Drop all of them into your game folder, right next to index.html.

The engine is already wired for this — you don't edit index.html.

Files
-----
manifest.json         Describes your app: name, colours, and icons.
sw.js                 Service worker that caches your game so it opens offline.
icon-192.png          App icon (192x192).
icon-512.png          App icon (512x512).
apple-touch-icon.png  Home-screen icon for iPhones/iPads (180x180).

What to edit
------------
1. manifest.json — set "name", "short_name", "background_color" and
   "theme_color" to match your game.
2. Replace the four icon PNGs with your own artwork (keep the same file
   names and sizes). They're placeholder Sastra icons for now.
3. sw.js — when you release an update, bump the CACHE name (e.g. "my-vn-v2")
   so players receive the new files instead of the cached old ones.

Note: PWAs only work over https:// (or http://localhost while testing).
The free static hosts in the "Publishing Your Game" docs all serve HTTPS,
so once your game is published, installing just works.
