Author: Peter Nguyen
Description: Dark-first personal blog theme for a site that writes in two registers — a technical log and a personal essay. Photographic banner, an archive ledger, and a deliberately different layout for each thread. Built for capturedbynguyen.com; not for distribution.

 *
 * Be Vietnam Pro was drawn for Vietnamese. Roughly a fifth of the posts here are
 * written in Vietnamese, with stacked diacritics that most display faces render
 * as collisions, so this is a content decision before it is an aesthetic one.
 * Newsreader carries the display voice. Self-hosted, because the site makes no
 * third-party requests and a font CDN is a tracker with a stylesheet.
