Manrope[wght].ttf declares family "Manrope ExtraLight" (default instance is wght 200)

## Summary

`ofl/manrope/Manrope[wght].ttf` declares its legacy family name as **`Manrope ExtraLight`**, because the `wght` axis defaults to 200 and name IDs 1/2 describe the default instance. Anything that reads name ID 1 — or instances statics from this file without overriding names — reports or produces "Manrope ExtraLight".

## Evidence

From `ofl/manrope/Manrope[wght].ttf` (current `main`):

```
name family(1) "Manrope ExtraLight"
name subfamily(2) "Regular"
name postScript(6) "Manrope-ExtraLight"
name typoFamily(16) "Manrope"
name typoSubfamily(17) "ExtraLight"
OS/2 usWeightClass 200
fvar wght min 200 default 200 max 800
```

`ofl/manrope/METADATA.pb` carries it too — the entry declared at `weight: 400` reads:

```
post_script_name: "Manrope-ExtraLight"
full_name: "Manrope ExtraLight"
```

## Why it matters downstream

Tools that read a font's name rather than its outlines report pages using Manrope as using Manrope ExtraLight, at every weight. Rendering is unaffected — outlines and per-instance weights are correct — so this is invisible in a browser and shows up only in design-handoff tools, font inspectors and asset catalogues.

It also propagates: packages that instance static webfonts from this file inherit the name. `@fontsource/manrope@5.3.0` ships woff2 named `Manrope ExtraLight SemiBold`, `Manrope ExtraLight Medium`, and so on. Filed separately at fontsource/font-files#162.

## Suggested fix

Set the default instance of the `wght` axis to 400 (Regular), so name IDs 1/2 describe Manrope Regular, or set name IDs 1/2/4/6 explicitly to the Regular instance while leaving the axis default. Most variable families on Google Fonts with a 400 default do not have this problem; Manrope's axis starting and defaulting at 200 is what exposes it.

Related: `upstream_info.md` records the upstream as https://github.com/aaronbell/manrope (the `sharanda/manrope` URL in METADATA.pb is deleted). The static webfonts in that repo's `fonts/webfonts/` **are** named correctly — `Manrope`, `Manrope Medium`, `Manrope SemiBold`, `Manrope`/Bold, `Manrope ExtraBold` — so the correct names exist upstream and are lost in the variable build.

Inspect ofl/manrope/Manrope[wght].ttf and ofl/manrope/METADATA.pb, then compare their names with the static files in the upstream fonts/webfonts/ directory. Trace how the variable font is generated and verify that the default or explicit names identify Manrope Regular while preserving the correct weight metadata.
