+Inno Setup 6 installs **per-user** to `%LocalAppData%\Programs\Inno Setup 6\`, not Program
+Files — that tripped up the first attempt to locate `ISCC.exe`.

+- **Don't double-compress.** Publishing with `EnableCompressionInSingleFile=false` and
+  letting Inno's LZMA2 do the work gives a ~51 MB setup vs ~70 MB, and the installed app
+  starts faster because there's no decompression at launch.
+- **Uninstall only removes the autostart entry if it points at the installed copy.** The
+  app's own Settings toggle writes the same `Run` value name, so an unconditional delete
+  would wipe out a portable build's autostart. This was a real bug caught in testing.
+- User data under `%AppData%\EbbesMemeClipboard` is deliberately preserved on uninstall;
+  only the re-downloadable `GifCache` is removed.
+- Verified end-to-end: silent install → files/shortcut/uninstall-entry present → app runs →
+  silent uninstall → everything removed, user data and unrelated autostart intact.
+- An installer does **not** fix SmartScreen warnings; only code signing does.
+
 Note: the published single-file exe takes **~10 seconds on first launch** before the tray
 icon appears (native library self-extraction to TEMP). Not a bug. Subsequent launches are
 faster.

-## Pending requests (not yet implemented)
+## Giphy integration notes
 
-From the user's most recent batch. **None of these are started.**
+**Tenor is dead.** The user originally asked for Tenor; research confirmed Google **shut
+down the public Tenor API on 2026-06-30** (corroborated by 9to5Google, Shacknews,
+Slashdot). Not buildable. **Giphy** was chosen instead and is what's implemented.
 
-### 1. Windows auto-start, with a toggle in Settings
-Straightforward. Write `HKCU\Software\Microsoft\Windows\CurrentVersion\Run`.
-**Important**: use `Environment.ProcessPath`, **not** `Assembly.Location` — the latter
-returns an empty string in single-file published mode. Add an `IAutostartService` +
-a checkbox in `SettingsWindow`.

-### 2. Tab/dropdown for meme sources (Local, Giphy)
-UI shell for multiple sources, plus the Giphy integration behind it.

-**Critical context — Tenor is dead.** The user originally asked for Tenor; research during
-planning confirmed Google **shut down the public Tenor API on 2026-06-30** (corroborated by
-9to5Google, Shacknews, Slashdot). It is not buildable. The user chose **Giphy** as the
-replacement. Notes:
-- `GET https://api.giphy.com/v1/gifs/search?api_key={key}&q={query}&limit={n}&rating=pg-13`
-- Response: `data[].images.{fixed_width,downsized,original}.url`
-- Free "beta" key is 100 req/hr — plenty for personal use. Production tier is ~$9k/yr and
-  irrelevant here. **The user needs to supply their own key** (add a field in Settings).
-- Giphy's ToS **requires a visible "Powered by GIPHY" badge** wherever results appear.
-  This is a real UI requirement, not optional attribution.
-- Build behind an `IGifProvider` interface so another provider can be swapped in later.
-- Remote GIFs must be **downloaded to a local cache file before** they can go on the
-  clipboard as CF_HDROP.
+- `GET https://api.giphy.com/v1/gifs/search?api_key={key}&q={q}&limit={n}&rating=pg-13`
+- Empty query falls back to `/trending` with the same parameters.
+- Response: `data[].images.{fixed_width,original}.url` — `fixed_width` for grid

-### 3. "Central store specific to the application for all local memes"
-**⚠️ STILL AMBIGUOUS — ASK THE USER BEFORE BUILDING.**
-The app *already* stores memes centrally in `%AppData%\EbbesMemeClipboard\Library`. When
-asked to clarify, the user selected "Something else" but the conversation moved on before
-they explained. Options offered (and rejected) were: (a) save Giphy results into the local
-library, (b) configurable library folder location. So it's something other than those two —
-**get a concrete description first.**
+**Untested by the assistant**: actual Giphy search results, remote thumbnail loading, and
+download-on-select were never exercised against the live API, because no API key was
+available. The code paths are written but unverified end-to-end — if something misbehaves
+once a key is entered, start with `GiphyGifProvider.SearchAsync` (JSON field names) and
+`GifCacheService.GetOrDownloadAsync`.
 
-### 4. Fix GIFs — "clicking a GIF doesn't copy/paste it correctly"
-User confirmed this specific symptom (not thumbnails, not crashes, not lag).
+---
 
-**Strong root-cause hypothesis (not yet verified — verify before/while fixing):**
-`ClipboardService` sets the `"PNG"` clipboard format from `firstFrame` — i.e. **frame 0 of
-the GIF re-encoded as a static PNG**. Chromium-based apps *prefer* the `"PNG"` format over
-everything else (that preference is exactly why it was added, to fix static-image pasting
-into Teams). So for a GIF, Teams/Discord grab the static first frame instead of the animated
-GIF → the GIF pastes as a still image.
+## Pending requests
 
-**Suggested fix**: skip the `"PNG"` format when the file is a GIF, so Chromium falls back to
-`CF_HTML` (which already carries the full animated `data:image/gif;base64,...` URI) or
-`CF_HDROP`. `ImageDecoding.IsGif()` already exists for the check. Keep `CF_DIB` so Paint
-still gets something. Test in both Teams and Paint, since these two want opposite things.
+### ⚠️ 1. "Central store specific to the application for all local memes" — STILL AMBIGUOUS

+were: (a) save Giphy results into the local library, (b) configurable library folder
+location. So it's something other than those two — get a concrete description first.
 
-**Also worth fixing while in there** (separate, minor, pre-existing):
-`ImageDecoding.DecodeFirstFrame` **ignores `decodePixelWidth` for GIFs** — it returns the
-`GifBitmapDecoder` frame before reaching the `DecodePixelWidth` logic. So GIF thumbnails
-decode at full resolution while static images are capped at 150px. A library with many
-large GIFs will use more memory than it should.
+### 2. Paste-send reliability ("Teams is sometimes too slow")
+Not yet addressed. Current delays in `AutoPasteService`: `FocusSettleDelay` 200ms (before
+Ctrl+V), `PasteSettleDelay` 400ms (before Enter). Both are fixed sleeps, so a slow app will
+still occasionally miss.
