   game icon on the .exe (rcedit), Linux, and the update check below.
 - **Updates**: the game (and a dedicated server) needs to notice when a new
   version is out, download what's needed and install it. See below.
+- **A single-player web version** (Paul, Nov 2026: after the playtest):
+  play straight from the download page, with "Download for the full game
+  and multiplayer" beside it. Godot's web export, single-threaded, on the
+  Compatibility renderer (WebGL 2). What we found (0.6.1):
+  - *The look:* rendered with that renderer (`build/web_look/`, from
+    `tools/site/shots.gd` run with `--rendering-method gl_compatibility`),
+    it's still clearly the game, but harsher: no volumetric fog or haze,
+    no SSAO/SSIL (darker, sharper shadows), deeper greens. Night and fire
+    light hold up. **The sea renders flat white**: `shaders/water.gdshader`
+    needs a Compatibility path. Ordinary distance fog would bring some
+    atmosphere back; grass density and tree counts likely need a lower
+    setting for browsers (speed not measured yet).
+  - *Single-player only:* browsers can't use ENet (UDP), and can't start
+    the Host Game or per-land server processes. Joining from a browser
+    would mean a WebSocket transport on the server, served over wss://
+    (a certificate per server): a separate, bigger job, if ever.
+  - *Saves* go in the browser's storage (IndexedDB): kept, but per browser
+    and lost if site data is cleared. Maybe an export/import button.
+  - *Input:* the pointer lock needs a click, and Esc releases it in the
+    browser, so the pause menu needs another key too (P).
+  - *Size and hosting:* the engine (godot.wasm, 39.5 MB) plus the game data
+    (about 22 MB) download first, then cache. Cloudflare Pages refuses files
+    over 25 MiB, so the .wasm has to live elsewhere (the Gitea release, or
+    another host) or be split.
+  - *Size of the job:* one step to build it and see how it runs, another to
+    fix the water, tune the graphics and controls, and put it on the page.
+- **Later, maybe:** Android tablets (Nov 2026: left for now). Most input is
+  already named actions, so a touch layer (stick, look, contextual buttons)
+  is possible; the Mobile renderer has the same lost effects as the web, and
+  a tablet can join but not host (no server processes).
 
 ### Updates (to design with the packaged builds)
 Needed because every network change bumps the protocol (12 as of P5), and
