Problem: the hexagonal refactor churns the backend tree for nine more phases; the UI delivery stack (web/ SPA, cmd/desktop Wails wrapper, compose/web image) must move to its own repo first so doc/layout rewrites land once on a backend-only tree. Change: - New repo git.hubris.network/dtoro/oikos-web (v0.33.0): web/, desktop/ (updateURL repointed to oikos-web releases), compose/, own CI (web + desktop jobs), own deploy script (CI-green gate, TOCTOU guard, version-tagged images, prune-to-3), own webhook receiver on :9798 + launchd unit, own compose project publishing the same 8091:80. - Cutover executed on mac-mini in order: oikos stack's web service stopped+removed, oikos-web project brought up on 8091; outer Caddy untouched (targets the published port) — serving + Authentik flow + /wails 404 quirk verified post-cutover. - Stripped from oikos: web/, cmd/desktop/, compose/web/, desktop CI workflow, ci.yml web job, Makefile ui/desktop/desktop-package/install targets, the compose web service, oikos-web from deploy.sh's fallback prune list; wails + go-keyring dropped from go.mod, vendor synced. - README / CONTRIBUTING / AGENTS.md / .agents dev+operations docs now point at the new repo; mbse + mascot design docs carry a path note. Risk: production SPA serving depends on the new pipeline now; rollback is versioned-image re-up of the old web service from a pre-split checkout (port 8091). Desktop builds installed before the split still check dtoro/oikos releases — one manual reinstall, noted in the oikos-web release notes. Verification: go vet, make test (race), make generate-check, golangci (no new findings; baseline down 400→365); post-cutover curls — localhost:8091 200, /wails/runtime.js 404, outer Caddy 302 Authentik.

CSS Calc 
Implemented from : https://drafts.csswg.org/css-values-4/ on 2023-02-17
Usage
Add CSS calc to your project:
npm install @csstools/css-calc @csstools/css-parser-algorithms @csstools/css-tokenizer --save-dev
With string values :
import { calc } from '@csstools/css-calc';
// '20'
console.log(calc('calc(10 * 2)'));
With component values :
import { stringify, tokenizer } from '@csstools/css-tokenizer';
import { parseCommaSeparatedListOfComponentValues } from '@csstools/css-parser-algorithms';
import { calcFromComponentValues } from '@csstools/css-calc';
const t = tokenizer({
css: 'calc(10 * 2)',
});
const tokens = [];
{
while (!t.endOfFile()) {
tokens.push(t.nextToken());
}
tokens.push(t.nextToken()); // EOF-token
}
const result = parseCommaSeparatedListOfComponentValues(tokens, {});
// filter or mutate the component values
const calcResult = calcFromComponentValues(result, { precision: 5, toCanonicalUnits: true });
// filter or mutate the component values even further
const calcResultStr = calcResult.map((componentValues) => {
return componentValues.map((x) => stringify(...x.tokens())).join('');
}).join(',');
// '20'
console.log(calcResultStr);
Options
precision :
The default precision is fairly high. It aims to be high enough to make rounding unnoticeable in the browser.
You can set it to a lower number to suit your needs.
import { calc } from '@csstools/css-calc';
// '0.3'
console.log(calc('calc(1 / 3)', { precision: 1 }));
// '0.33'
console.log(calc('calc(1 / 3)', { precision: 2 }));
globals :
Pass global values as a map of key value pairs.
Example : Relative color syntax (
lch(from pink calc(l / 2) c h)) exposes color channel information as ident tokens. By passing globals forl,candhit is possible to solve nestedcalc()'s.
import { calc } from '@csstools/css-calc';
const globals = new Map([
['a', '10px'],
['b', '2rem'],
]);
// '20px'
console.log(calc('calc(a * 2)', { globals: globals }));
// '6rem'
console.log(calc('calc(b * 3)', { globals: globals }));
toCanonicalUnits :
By default this package will try to preserve units. The heuristic to do this is very simplistic. We take the first unit we encounter and try to convert other dimensions to that unit.
This better matches what users expect from a CSS dev tool.
If you want to have outputs that are closes to CSS serialized values you can pass toCanonicalUnits: true.
import { calc } from '@csstools/css-calc';
// '20hz'
console.log(calc('calc(0.01khz + 10hz)', { toCanonicalUnits: true }));
// '20hz'
console.log(calc('calc(10hz + 0.01khz)', { toCanonicalUnits: true }));
// '0.02khz' !!!
console.log(calc('calc(0.01khz + 10hz)', { toCanonicalUnits: false }));
// '20hz'
console.log(calc('calc(10hz + 0.01khz)', { toCanonicalUnits: false }));
