[codex] Add first slice engagement model

[Radical-Coder]

What changed

Adds a FIRST SLICE engagement section that explains how work starts:

• diagnostic call to map system risk
• alignment milestone to inspect code/deployments/providers before rebuilding
• first production slice with PR/deployment/runbook/proof output
• practical starting material buyers should bring

Why

The vault and Upwork notes consistently frame Ryan's strongest work as bounded, proof-first rescue and hardening rather than broad open-ended builds. This turns the CTA into an understandable buying path.

Validation

• npm run build

📝 Walkthrough

Walkthrough

A new "Engagement Model" section is added to index.html before the existing Standards section. New CSS classes define a 3-column step-card grid, typography, a note panel, and an actions row; a mobile breakpoint collapses the grid to one column. The HTML inserts three numbered steps with proof outputs, a highlighted note, and a mailto CTA.

Changes

Engagement Model Section

Layer / File(s)	Summary
Engagement Model CSS (desktop + responsive) index.html	Adds CSS classes for the 3-column engagement grid, step card borders/padding, step number/title/description/proof typography, an emphasized note panel, and an actions container. Mobile breakpoint rules reflow the grid to a single column and remove inter-step left borders.
Engagement Model HTML content and CTA index.html	Inserts the Engagement Model section before Standards with three numbered steps (01–03), each containing a title, description, and proof output block; a highlighted "Useful starting material" note panel; and a "Start with a Diagnostic" mailto CTA button.

Poem

A bunny hops in with a three-step plan,
Grid columns aligned, neat cards in a span,
📬 One mailto click to start the dance,
On mobile it stacks — no squinting askance,
🐇 "Step 01 begins!" the rabbit declares.

1232-1237: ⚡ Quick win

Add a header anchor for the new Engagement section.

The new FIRST SLICE section is a primary buying-path element, but there’s no direct #engagement link in the sticky nav. Adding one will improve discoverability and shorten user path-to-CTA.

Closing as superseded by #14. The first-slice buying path is now covered by the current service ladder, process section, and AI rescue route on the survivor branch. Keeping this closed avoids merging older section structure back into index.html.
