## Watch out
The README says "Twenty-four languages, plus Vue, Svelte and Astro..." in words, and lists the languages in a bullet a few lines up. Every PR that adds a language (Julia, Bash, GLSL, PowerShell landed in the same week) edits both lines, so they all conflict with each other and each needs a rebase after the previous one merges.

## Decided
When several language PRs land together, resolve their README conflicts by keeping main's count line and fix the count once in a follow-up after the batch merges, instead of rebasing each PR through CI again.

In the code: README.md, the "N languages, plus Vue..." sentence and the "symbols only" language list; src/graph/generic.ts registry rows are the source of truth for what's supported.
