feat: load Aldrich webfont for #1137 logo SVG (#1138)

Adds Aldrich webfont so the merged #1137 logo renders in the intended
typeface.

## Problem
The inline SVG logo merged in #1137 declares `font-family="Aldrich,
monospace"` in `public/index.html` and `public/home.js`, but the page
never loaded the Aldrich font face. Browsers silently fell back to
monospace.

## Fix
Self-hosted webfont:
- `public/fonts/aldrich-regular.woff2` — Regular 400, ~16KB, downloaded
from Google Fonts (latin subset). Self-hosted to avoid third-party CDN
dependency, privacy concern, and FOUT delay.
- `@font-face` declaration added at the top of `public/style.css` with
`font-display: swap`.

Aldrich only ships in 400; the SVG `font-weight="700"` on the wordmark
synthesizes bold (matches the design intent of #1137).

## TDD
- Red commit: E2E test asserting `document.fonts.check('1em Aldrich')`
is true and the navbar SVG `<text>` `font-family` contains "Aldrich".
Without the font face declaration, both assertions fail on an assertion
(not a build error).
- Green commit: adds the woff2 + `@font-face` rule, both assertions
pass.

## Files
- `public/fonts/aldrich-regular.woff2` (new, 16460 bytes)
- `public/style.css` — `@font-face` rule
- `test-e2e-playwright.js` — new test
