Jannis Braun de2ef10129 fix(brand): home tile = Element 1 with #000 bg, drop tile lavender
Iterating-by-paint-over wasn't working. Going back to first
principles: the brand IS the badge — full Element 1 mass, mark with
its own internal padding, dark frame around it. That's what reads as
"Backspace" on every other surface (dock, taskbar, favicon, apple-
touch). The sidebar home tile should look the same.

The earlier "ugly grey" complaint about Element 1 in the sidebar
came down to one specific colour mismatch: the source SVG's
#1d1d1b (warm near-black) sat next to the sidebar's #1a1a23 (cool
near-black) and read as an off-grey rectangle. Fix: in the generator,
do a string-replace `#1d1d1b → #000000` on app-icon.svg before
rendering logo.png only — every other output (.icns, .ico, favicons,
PWA) keeps the original brand `#1d1d1b`. Pure black against the
sidebar's #1a1a23 reads as a deliberately darker tile, not a hue
mismatch.

Reverts the SpaceSidebar lavender-tile workaround: with the badge
filling the tile via object-cover, the button's overflow-hidden +
rounded-[20px → 13px] morph already animates the badge cleanly.
backgroundStyle for type === 'dm' returns undefined again; deps trim
back to what they were.

Determinism gate verified — only logo.png changed (other 21 outputs
byte-identical across two regen runs).

# Icon Generator
Regenerates every brand artefact from `assets/brand/*.svg`:
- macOS `.icns`, Windows `.ico`, Linux per-size PNGs (`packages/desktop/build/`)
- Tray icons for all three platforms (`packages/desktop/resources/`)
- Web favicons, PWA manifest icons, maskable, in-app `logo.png` (`packages/web/public/icons/`)
## When to run
After changing any file under `assets/brand/`, **or** after bumping `sharp`,
`png-to-ico`, or `png2icons` in the root `package.json`. Commit the diff in
the same PR.
```bash
pnpm gen-icons
git status # review which files changed
git add packages/desktop/build/ packages/desktop/resources/ packages/web/public/icons/
git commit -m "chore: regenerate brand icons"
```
(Stage explicit paths rather than `git add -A` — the generator only writes to those three directories, and an unrelated working-tree change shouldn't accidentally land in a "regenerate icons" commit.)
## Determinism
Output is byte-stable for a given lockfile. The same SVGs in produce the
same PNG/ICO/ICNS bytes out, every time, on every OS — Sharp uses resvg
internally and writes deterministic PNGs, png-to-ico and png2icons don't
embed timestamps.
**Caveat:** byte-stability is *not* guaranteed across version bumps of
the three encoder deps. After a Renovate / dependabot PR upgrades any of
them, run `pnpm gen-icons` once and commit the resulting diff inside the
same PR. That follow-up commit isn't an artwork change — it's encoder
output drift, and gating it inside the dep PR keeps the artwork-change
git history clean.
## Source SVGs
| Brand source | Drives |
|---------------------------------|-----------------------------------------------|
| `assets/brand/app-icon.svg` | Every full app icon, all favicons, PWA, in-app `logo.png` (with `#1d1d1b → #000` bg swap for sidebar contrast) |
| `assets/brand/mark.svg` | Win/Linux tray, PWA maskable inner mark |
| `assets/brand/mark-mono-dark.svg` | macOS menu-bar template (alpha + black) |
`Artworks-Backspace/` is the design archive — never read by this script.
