% Aesthetic Computer --- Stack Knowledge (DevOps map poster)
% arxiv-style LaTeX poster. Build on neo or in the devcontainer (this Mac has no
% xelatex):  cd stack && latexmk -pdf stack-poster.tex   (or: pdflatex twice)
% Requires the `tikzposter` class (TeX Live full has it).
%
% Data assembled 2026-07-15 from the monorepo (package.json + lockfiles + ncu),
% infra config (lith/, session-server/, oven/, feed/, grab/, oven-edge/), and
% vendor/env-name mapping. Dollar costs are NOT in the repo except the one marked
% real; every other cost cell is "usage" or "needs input" --- do not invent them.
%
% Vendor "logos": represented as brand-coloured chips (self-contained so this
% builds anywhere). Dropping in real logo art / OS favicons is a follow-up pass ---
% put PNGs in stack/logos/ and swap the \chip macro for \includegraphics.

\footnotesize
Build: \texttt{cd stack \&\& latexmk -pdf stack-poster.tex} on \textbf{neo} or the devcontainer.
Data spine lives in \texttt{stack/}. Cost cells marked \tbd{} need a billing snapshot; \usg{} = usage-metered (varies).
Real logos / OS favicons: drop PNGs in \texttt{stack/logos/} and swap the \texttt{\textbackslash chip} macro.
