Aman Bhargava 35a019d324 decks: real rendered equations + theorem boxes (self-hosted MathJax), not decorative glyphs 
Aman's feedback was right — the stat-card template printed single vars (H,
C, R<C) with no rendered math. Replaced with self-hosted MathJax tex-svg
(no CDN, zero external requests): full equations (entropy, chain rule,
MI=KL, Sigma_N precision, HMM factorization, Viterbi argmax) and boxed
named theorems (AEP, source/channel coding, Kraft-McMillan). Spacing
tightened so multi-equation slides fit 100vh.

aman.holdings

Aman Bhargava's personal lecture site: the Engineering Science abridged series plus extensions and AI-augmented lectures, presented in the Cartesian Theatre player.

Architecture

  • Cloudflare Pages serves everything in public/ (viewer code, transcripts, slides, telemetry chunks — every file stays under the 25 MiB Pages limit).
  • Cloudflare R2 (aman-holdings-media) holds the multi-gigabyte media masters. functions/media/[[path]].ts serves them same-origin at /media/<key> with full byte-range support, so seeking is instant and no CORS or crossorigin plumbing is needed.
  • No servers. Storage is ~$0.015/GB-month; R2 egress is free.

Layout

public/
├── index.html                      # lecture library landing page
└── lectures/<slug>/                # one Cartesian Theatre package per lecture
functions/media/[[path]].ts         # R2-backed range-serving media route
scripts/upload-media.sh             # push a media master to R2
wrangler.toml                       # Pages config + R2 binding

Adding a lecture

  1. Copy the theatre package (everything except media/) to public/lectures/<slug>/.
  2. Edit DEFAULTS.mediaSrc in its app.js to /media/lectures/<slug>/<file>.mp4.
  3. scripts/upload-media.sh <local-master> lectures/<slug>/<file>.mp4
  4. Add a card to public/index.html.
  5. Deploy.

Deploy

npx wrangler pages deploy public --project-name aman-holdings

First deploy creates the project. Custom domain aman.holdings is attached once in the Cloudflare dashboard (Pages → aman-holdings → Custom domains).

Local dev

npx wrangler pages dev public

The local R2 binding starts empty; media 404s locally unless you seed the local bucket. Everything else works.
