Signal CGM — Brand Extension v1

Date: April 2026 Parent system: sttil-brand-system-v1.md Status: Active

---

1. Inheritance from STTIL Solutions

Signal CGM is a product expression of the STTIL Solutions brand. It inherits:

• Full teal scale (teal-950 → teal-50)
• Full tangerine scale as accent
• Plus Jakarta Sans / Inter / JetBrains Mono type stack
• All semantic status colors
• All spacing, radius, and shadow tokens
• "Never loud, always clear" visual principle

What shifts for Signal CGM:

• Clinical precision takes priority over narrative warmth
• Data density is higher — tables and status indicators are the primary surface
• Urgency communication is more explicit (regulatory deadlines, expiry countdowns)
• Dark mode is the operational default (dashboard use)
• Tangerine appears at the PA Required badge and highest-priority row — the two highest-stakes signals in the UI

2. Tone Shift

STTIL Solutions	Signal CGM
Warm, narrative, brand story	Precise, operational, clinical
Speaks to the vision	Speaks to the daily task
"Built for people bearing real operational weight"	"PT-00142 · 4 days left · PA Required"
Earns trust through specificity	Earns trust through accuracy

Signal CGM copy should read like a knowledgeable billing colleague, not a software vendor.

6. Worklist Table Conventions

• Patient ID column: JetBrains Mono, font-weight: 700. On priority row, color shifts to tangerine-300 (#FFB070 dark) or tangerine-700 (#903A14 light).
• Priority Score: JetBrains Mono, 16px, font-weight: 500. High (≥75): tangerine-text. Mid (40–74): text-secondary. Low (<40): text-muted.
• Days Left: JetBrains Mono. Critical (<30): error red. Warning (30–59): tangerine-text. OK (60+): text-primary.
• Top priority row: One priority-row-bg wash + ★ TOP PRIORITY micro-label in tangerine-text. Only one per view.
• Tangerine CTA: Only on the top priority row's action button.
• Table header: teal-800 background, uppercase text-muted labels at font-size: 10.5px, letter-spacing: 0.06em.

7. Pitch Deck Usage (Supplier-Facing)

Slide structure:

• Title / section slides: teal-900 background, warm-white headline, teal-300 sub-label
• Content slides: neutral-0 background, teal-700 section headers
• Data charts: teal-500 primary series, tangerine-400 for the key comparison metric
• Call-out boxes: tangerine-100 background, tangerine-700 text, tangerine-500 left border (4px)
• The two-curve workload graph (appeals ↓ / proactive outreach flat) is the hero visual

Supplier-facing language:

• Lead with the denial rate: "35–45% first-pass denial rate for CGM claims"
• Show the crossover point: "Month 4 — proactive outreach volume replaces appeals volume"
• No AI language. No "platform." Call it a worklist tool.

---

8. LinkedIn / Social Posts

Format — Signal CGM announcement post:

• Carousel: 5 slides (hook → problem data → product shot → outcome → CTA)
• Cover slide: teal-900 background, warm-white headline in Plus Jakarta Sans 700, one tangerine data point
• Data slides: neutral-0 background, teal headers, JetBrains Mono for percentages
• One tangerine accent per slide — never two
• CTA slide: teal-600 background, white text, simple ask

Tone: Specific, grounded, no hype. Use actual regulatory dates and denial rates.

9. Billing Company-Facing vs. Supplier-Facing Materials

Dimension	Supplier-Facing	Billing Company-Facing
Primary pain	"My staff is buried in appeals"	"Our clients have high denial rates costing us rework"
Value frame	Prevent denials before they happen	Offer clients a differentiated CGM compliance tool
Regulatory hook	CMS competitive bidding deadline, PA affirmation rate	Same — but also enrollment moratorium / compliance risk
Product language	"Signal CGM worklist"	"Signal CGM — white-label ready" (future Phase 2)
Visual tone	Warm, operational, data-dense	Colder, more corporate, teal-900 dominant
CTA	"Try it with your next CSV import"	"Schedule a 30-minute walkthrough"

---

10. PHI Note on All Materials

All Signal CGM marketing materials must include, at minimum in footer or fine print:

"Signal CGM does not store patient names, dates of birth, or contact information. Only patient_id (your internal MRN or account number) is used as the crosswalk key."

This is a trust signal, not a legal disclaimer. Put it where a billing manager will see it.
