tiennm99 b2834749c9 feat: v0.3.0 — Tier A parity, per-kind CSS, llm.txt, a11y baseline
Headline outcomes:
- Feature parity with Stack/PaperMod on Tier A polish: breadcrumbs
  (+BreadcrumbList JSON-LD), prev/next post navigation (rel=prev/next),
  language switcher UI (gated on hugo.IsMultilingual), code-copy button
  polish, <details> styling.
- Per-page-kind CSS bundles: core loads everywhere; home/single/archive/
  search bundles load only where needed. Frees ~1 KB gz from non-post
  pages. code-copy.js gated to post pages.
- Lighthouse-relevant network polish: Pagefind UI CSS preload-swap,
  conditional preconnect to giscus.app on comment-enabled posts,
  hreflang alternates on multilingual sites, <meta name=theme-color>
  light/dark variants, aria-pressed SSR-rendered on theme-toggle.
- WCAG AA contrast: --tsuki-fg-subtle darkened to #6b6b6b (light); was
  3.54:1 on bg, now 5:1. Pagination disabled uses --tsuki-fg-muted
  without opacity compound. Header tap targets bumped to 40×40; pagination
  to 44×44.
- i18n: full i18n/en.yml mirror (~50 keys); render-heading aria-label
  i18n-driven via linkToSection key; new keys for breadcrumb*, prevPost,
  nextPost, copyCode, copiedCode.
- Discovery: /llm.txt output format (llmstxt.org) on home; Speculation
  Rules opt-in via params.prefetch.enable.
- <html lang> fallback: site.Language.LanguageCode → Lang → "en"
  (was hard-coded "vi").

Per-kind bundle gz sizes on demo: home 3673 / post 4167 / list 2897 /
archives 3363 / search 3179 B (all under 4200 B cap).

tsuki (月)

build license Hugo CSS

A Hugo blog + personal portfolio theme. The homepage is the portfolio — bio, featured projects, recent posts. Posts live at /post/. Vietnamese-first typography, View Transitions on navigation, Pagefind search, Giscus comments.

月 (tsuki): the moon. Quiet, observed, returned to. Companion to bonsai in the same naming family.

→ Live demo

Status

v0.1.0 — initial release. See CHANGELOG.md.

Features

  • Blog — posts, tags, categories, year-grouped archive, paginated post list
  • Personal portfolio on the homepage — driven by data/profile.yaml + data/projects.yaml, no separate /portfolio section
  • Search — Pagefind, zero-runtime, indexed at build time
  • Comments — Giscus (GitHub Discussions)
  • Vietnamese-first — diacritic-safe typography, native vi date formats, ASCII heading IDs
  • Dark mode — prefers-color-scheme + persistent toggle, no flash of wrong theme
  • View Transitions API — smooth same-document navigation in supporting browsers
  • Table of contents — auto-mounted on long posts, sticky on wide viewports, IntersectionObserver active highlight
  • No build step — pure Hugo + browser ES modules. No SCSS, no TypeScript, no bundler in the theme
  • Light — CSS ≤ 4 KB gz, JS ≤ 1 KB gz (excluding Pagefind UI)

Quick start

git submodule add https://github.com/tiennm99/tsuki.git themes/tsuki
echo 'theme: tsuki' >> hugo.yaml

Full installation guide (submodule, Hugo Module, Pagefind setup, required site config): docs/installation.md.

exampleSite/hugo.yaml is a complete working example.

Documentation

Search and comments

Search uses Pagefind, built post-Hugo via npx pagefind --site public. tsuki pins Pagefind in its own package.json for submodule consumers; Hugo Module consumers install Pagefind in their own site (see docs/installation.md). No runtime dependency.

Comments use Giscus. Generate config at giscus.app and add to params.comments.giscus.* to enable. Defaults to off.

Browser support

Modern evergreen browsers. View Transitions and :has() are progressive enhancements; the theme remains functional without them.
