[diecasting]

Summary

Isolated, minimal fix for cramped service-page section titles and broken card grids across the 7 languages (EN/DE/ES/FR/IT/JA/KO).

Files changed (exactly 2):

1. assets/css/custom.css — add a self-contained Tailwind-equivalent utility shim (36 classes) covering the utilities the structured service partials use but that are missing from the committed Tailwind v4 compiled main.css (e.g. py-12/sm:py-16, grid-cols-1/lg:grid-cols-3, gaps, dark variants). Restores vertical rhythm and card grids.
2. config/_default/params.toml — preserve the previously approved showEdit = false (removes visitor-visible edit anchors on service pages).

Root cause: the service section partials were added after assets/css/compiled/main.css was compiled. tailwind.config.js has no content block and CI only runs hugo --minify (no Tailwind rebuild), so 36 utilities were absent from the bundle. This patch is an additive CSS shim only — no partial/template/content/SEO/analytics/config changes, and main.css is not recompiled here.

Verification

• git diff --check clean; PR contains exactly the 2 files above.
• Hugo build passes (exit 0) on the branch.
• 36 utility classes passed static review: all 36 are actually used by the service partials; no orphan classes, no duplicate selectors, no specificity conflicts with main.css (custom.css is bundled last).

Known limitations / out of scope

• 28/35 service pages were built locally and covered by the spacing check. The die-casting-tooling slug is not built in any of the 7 languages (7 pages) and remains unverified — a build/content gap, not introduced by this patch.
• mobile de/cnc-machining has a pre-existing horizontal overflow caused by the theme's base text-4xl (36px) rendering a long unbreakable German title; this patch does not modify text-4xl and does not fix it. Recommended as a separate follow-up (e.g. overflow-wrap/hyphens).
• Verification used DOM computed-style metrics (padding / grid / overflow / anchor count), not pixel-level visual regression.
• Production is not yet deployed; this is a Draft PR for human review.
• The Tailwind full recompile fix (scan the service partials and regenerate main.css in CI, then remove this shim) is not part of this PR.
