Thanks for the update to the techniques docs. One high‑severity fix is needed before merge.

[HIGH] Missing frontmatter; page title rendered as body text

Location: https://github.com/tact-lang/mintlify-ton-docs/blob/b025787e285117b90fde9b9afa584fad875b4228/techniques/gas.mdx?plain=1#L1-L1

Description:
The YAML frontmatter was removed and replaced by an in‑body H2 ## title: "Estimate gas usage in TON contracts". The site expects page metadata (including the title) in frontmatter, with no visible in‑body H1; rendering the title: key as body text breaks metadata, disrupts heading hierarchy/TOC, and conflicts with the site’s title handling (see https://github.com/tact-lang/mintlify-ton-docs/blob/main/contribute/style-guide-extended.mdx?plain=1#L282-L284).

Suggestion:
Restore YAML frontmatter and remove the in‑body “title” heading.

Re-deployed: View deployment

I'm not sure if Mintlify's bot will pick up new updates here, because previously deployments were skipped for this branch and all other branches that were moved from the previous org/repo place.
