Keryx visual identity and store asset kit

Approved: 26 August 2026. Mark revision: 7 September 2026.

This document is the P2-01 visual-identity brief and store asset-kit specification for Keryx for SafeCall. It applies the P0-01 name hierarchy, records the canonical app mark, defines wordmark/palette/usage rules, and inventories current assets and remaining gaps.

It does not claim that a wordmark SVG/PNG was produced, that store listing graphics are final, that launcher metadata casing is fixed, or that a website brand kit is live. Android adaptive / round / monochrome assets and the megaphone mark revision are in source as of 7 September 2026.

Purpose and non-goals

Purpose

• Approve identity rules so listings, screenshots, web pages, and app chrome stay consistent with SafeCall companion positioning.
• Inventory the master icon and platform derivatives; record launch gaps.
• Assign ownership, versioning, and export procedure for later artwork work.

Non-goals

• Redesigning the icon or regenerating mipmaps / AppIcon sets in this item.
• Producing wordmark artwork files.
• Changing Android/iOS/Flutter display names in source (later implementation).
• Final Play feature graphic or screenshot production — spec in store-screenshot-kit.md (P2-03); PNG export #123/#125.
• Publishing live web brand pages — spec in public-web-pages.md (P2-04); HTTPS deploy deferred.

Approved identity hierarchy

Layer	Name / role
Legal publisher / store seller	sourcectl (Copyright © 2026 sourcectl)
Product umbrella	Wantok
Contracted platform	SafeCall
Public / in-app product name	Keryx for SafeCall
Launcher label (home screen)	Keryx
iOS / App Store bundle ID	com.sourcectl.keryxapp (amended 29 August 2026)
Android / Play application ID	com.sourcectl.keryx

Keryx is SafeCall’s administrator-only mobile notification companion. It is not a standalone consumer product, not owned by BleuVista or AlertHub, and must not be presented as independently usable without SafeCall.

Naming in visual contexts

Context	Use
App Store / Play listing title	Keryx for SafeCall
In-app product title / About	Keryx for SafeCall
Home-screen / launcher icon label	Keryx
Icon glyph	Mark only — no wordmark baked into the app icon
Store / web lockup next to icon	Text wordmark Keryx for SafeCall (artwork TBD)
Czech public materials	Same hierarchy; localized lockup via #108

Do not use lowercase keryx as the sole public product name in store or web chrome. Current source still uses lowercase launcher metadata in places — that is a gap for implementation, not an approved visual rule.

Icon system

Canonical source

• Editable: keryx/assets/icon/keryx_icon.svg
• Master PNG: keryx/assets/icon/keryx_icon.png — 1024×1024 RGB, no alpha (opaque).
• Adaptive foreground: keryx/assets/icon/keryx_icon_foreground.png — 1024×1024 RGBA; megaphone only, padded into the Android 66% safe zone.
• Monochrome: keryx/assets/icon/keryx_icon_monochrome.png — white silhouette on transparent (Android 13+ themed icons).
• Previous mark: keryx/assets/icon/keryx_icon_v1_shield.png (shield + signal arcs; superseded 7 September 2026).
• Concept: white geometric megaphone (cone, mouthpiece, short handle; facing right; no sound-wave arcs) on a solid deep-blue field — herald / announcement. Mark only; no wordmark.

Measured mark colors (from master PNG)

Role	RGB	Hex
Field / primary blue	0, 48, 135	#003087
Mark / on-field	255, 255, 255	#FFFFFF

QA checklist (must pass before submission)

Check	Requirement
Safe zone	Critical megaphone cone and handle remain clear inside platform masks (iOS squircle, Android adaptive)
iOS marketing 1024	Opaque; no transparency; no rounded corners baked in
Android adaptive	Foreground/background layers or verified full-bleed; round/legacy variants reviewed
Monochrome	Android thematic / monochrome adaptive asset produced and legible
Small sizes	Legible at ~29–48 px equivalents
Dark / light frames	Blue field remains distinct on light and dark store backgrounds
Masking	No essential detail clipped at edges after mask

Platform derivatives and gaps

Asset	Path / location	Status
Editable SVG	keryx/assets/icon/keryx_icon.svg	Ready
Master icon	keryx/assets/icon/keryx_icon.png	Ready (1024 RGB opaque)
Adaptive foreground / mono	keryx/assets/icon/keryx_icon_foreground.png, keryx_icon_monochrome.png	Ready
iOS AppIcon set	keryx/ios/Runner/Assets.xcassets/AppIcon.appiconset/	Regenerated 7 September 2026 — 1024 marketing icon is opaque RGB
Android adaptive / round / legacy	mipmap-anydpi-v26/ic_launcher.xml, ic_launcher_round, mipmap-*/ic_launcher.png	Ready (navy field + padded megaphone; monochrome layer present)
Notification status bar	keryx/android/app/src/main/res/drawable/ic_stat_keryx.xml	Ready (white silhouette)
iOS / Android launch	LaunchImage.imageset, drawable/launch_background.xml	Ready (navy field + mark)
Web icons	keryx/web/icons/, keryx/web/favicon.png	Present — secondary; not store submission
macOS icons	keryx/macos/Runner/Assets.xcassets/AppIcon.appiconset/	Present — out of public launch scope (macOS excluded)

Remaining gaps: wordmark artwork files; fix leftover lowercase launcher metadata to Keryx where it still appears. Re-export with dart run flutter_launcher_icons from keryx/ after any master change.

Wordmark

Topic	Approved rule
Lockup text (EN)	Keryx for SafeCall
Treatment until artwork exists	Typeset lockup (no invented third-party logo mark); pair with the app icon mark
UI typography	Prefer platform system UI fonts (SF / Roboto / Material defaults) for in-app chrome
Store / web display	Sans lockup; do not introduce a novelty display face that fights SafeCall family materials
Czech	Localized product lockup under #108; keep companion hierarchy

No wordmark SVG/PNG exists in-repo. Closing this item approves the text and usage rules, not shipped artwork.

Palette and type

Launch palette

Token	Hex	Use
keryx-blue	#003087	Icon field; primary brand accent for Keryx-marked surfaces
keryx-on-blue	#FFFFFF	Icon glyph; text/icons on keryx-blue
Neutrals	System / SafeCall page neutrals	Body copy, store frames — do not invent a second full theme here

Public install/legal pages per public-web-pages.md (P2-04) should follow the host site’s SafeCall/sourcectl page system and use keryx-blue only where a Keryx mark accent is needed.

Type

• In-app: platform defaults.
• Marketing lockup: clean sans; weight hierarchy that keeps Keryx primary and for SafeCall clearly subordinate companion phrasing.

SafeCall relationship rules (visual)

• Always show Keryx as a SafeCall companion, not an independent acquisition product.
• Do not use BleuVista or AlertHub marks as Keryx owners or parents.
• Store screenshots and feature graphics must show administrator QR / friendly categories per store-screenshot-kit.md (P2-03) — not generic ntfy branding.
• No visual promise of guaranteed emergency delivery (align with safety claims).

Ownership, versioning, and export

Topic	Rule
Owner / approver	Thomas Minitsios (P0-05 RACI)
Change control	Any master-mark or lockup change requires this owner’s approval and a roadmap/note touch
Versioning	When the mark changes, bump a documented asset revision (date + short note in release evidence) and regenerate platform derivatives
Export procedure	Rasterize keryx_icon.svg to the 1024 PNG masters, then from keryx/ run dart run flutter_launcher_icons (config in pubspec.yaml). Asset revision 7 September 2026 executed this path.
Secrets	No store signing material in asset folders

Evidence handoffs

Work	Owner
Adaptive / round / monochrome + re-export	Done 7 September 2026 (megaphone revision)
Wordmark artwork files	Later design implementation guided by this brief
Launcher / Flutter title casing to approved names	Later implementation / P3 metadata
Listing copy using approved names	store-listing-copy.md (P2-02)
Screenshots / feature graphic	store-screenshot-kit.md (P2-03); PNG export #123/#125
Public web pages	public-web-pages.md (P2-04); HTTPS deploy
Czech lockup parity	#108

Explicit non-claims

Closing #104 approved this brief. The 7 September 2026 revision ships the megaphone mark and adaptive kit. It still does not:

• claim a wordmark SVG/PNG was produced;
• claim store listing graphics are final;
• claim app/Android/iOS metadata casing is fixed;
• claim a website brand kit is live.

Review record

• Status: approved as the P2-01 visual identity and store asset-kit specification. Mark revised 7 September 2026 (shield → megaphone; adaptive / round / monochrome generated).
• Date: 26 August 2026 (brief); 7 September 2026 (mark revision).
• Approver: Thomas Minitsios under the P0-05 RACI.
• Depends on: P0-01 identity decision, strategy.md, safety-claims.md.
• Evidence sources: keryx/assets/icon/keryx_icon.svg and keryx_icon.png (measured palette), platform icon trees under keryx/ios, keryx/android, keryx/web.
