feat(ui): the M of the wordmark is the logo

The stylised M replaces the letter M in "MeshBay" at the top left; `eshBay` beside it stays text. **The source artwork is now in git.** It was in `QE/`, which is gitignored, so it would not have survived a clone — and the tree is about to be moved to another machine. `assets/brand/` holds the original and the `convert` command that derives the 10 KB nav asset from it (trimmed, 72px tall for a picture shown at 30, so it survives a 2× screen). Verified: the documented command reproduces the committed file byte for byte. The derived file is in `_ASSETS`, which is what the `/a//` fingerprint is computed from. A file missing from that list is a file whose change never moves the URL, so a browser holding the old one never asks again — the comment on that list says so, and a logo is exactly the kind of asset one would forget. Its URL is resolved from `import.meta.url`, so the hub's fingerprinted path and the application's `app://` scheme both come out right without either being named in the source. **The two sizes are independent, and that took four rounds to get right.** The picture's height was written in `em` — a fraction of the lettering — so every adjustment to the text resized the picture by the same stroke and the ratio between them could never change. The operator spotted the coupling before I did ("si on change la taille du M, tu vas encore tout décaler"). The height is in pixels now: `font-size: 1.375em` (22px) and `height: 30px`, two knobs that move one thing each. The vertical nudge went with it — it was correcting a misalignment I was causing myself. Also: the wordmark blue goes one step down from sky-400 towards sky-500. It sat brighter than the picture next to it, which made the two read as different materials rather than one object. A note on how this went wrong first: I checked the result on a mock HTML page I wrote, not in the application. The picture was loading the whole time, but at 25px against a 29px line box it was *smaller* than the letters, so the wordmark read as unchanged and the report was "none of what I asked for was done". Every size since has been measured in the running window over CDP. 883 tests pass. Co-Authored-By: Claude Opus 5
