Notice: Engineering compliance draft for Mareante (not yet reviewed by an independent attorney).

Nuno Ribeiro, operating as a Swiss sole proprietorship (Einzelunternehmen) trading as "Mareante", is committed to providing an accessible, usable experience for all individuals, including persons with disabilities.

We target modern digital accessibility standards in alignment with:

  • The European Accessibility Act (EAA) — Directive (EU) 2019/882 on accessibility requirements for products and services;
  • Harmonised European Standard EN 301 549 (Accessibility requirements for ICT products and services);
  • The Web Content Accessibility Guidelines (WCAG) 2.1 Level AA published by the World Wide Web Consortium (W3C).

2. Regulatory Status: Microenterprise Exemption (Article 4(5) Directive (EU) 2019/882)

Under Article 4(5) of Directive (EU) 2019/882, microenterprises providing services (enterprises employing fewer than 10 persons with an annual turnover or balance sheet total not exceeding €2 million) are exempt from mandatory EAA accessibility requirements and compliance assessment obligations.

Mareante operates as a sole proprietorship qualifying as a service microenterprise under Commission Recommendation 2003/361/EC and is therefore statutorily exempt under Article 4(5) of the Directive. Nevertheless, Mareante voluntarily implements and targets WCAG 2.1 Level AA conformance as an engineering quality standard.

The Mareante platform (mareante.nuuno.art) targets WCAG 2.1 Level AA conformance across its web application:

  1. Semantic HTML5 Architecture:
  2. Explicit landmark roles (<main>, <header>, <nav>, <aside>, <section>);
  3. Hierarchical heading structures (<h1>–<h6>);
  4. Clean data tables and lists.
  1. Keyboard Operability & Visual Indicators:
  2. Full keyboard accessibility across interactive elements without mouse dependency;
  3. High-contrast visible focus indicators (:focus-visible);
  4. Logical tab sequencing across multi-step forms and plan reviews.
  1. Assistive Technology Support & Live Regions:
  2. Dynamic status changes, run progress, and chat messages announced using aria-live="polite" to avoid disorienting screen reader users;
  3. ARIA attributes (aria-expanded, aria-controls, aria-label) applied to stateful UI controls.
  1. Visual Ergonomics:
  2. Minimum text contrast ratio of at least 4.5:1 for standard text and 3:1 for large text;
  3. Typography scales smoothly with user system preferences;
  4. No flashing elements exceeding three flashes per second.
  1. Full-Duplex Voice Modality (FR-VC-01):
  2. For users with motor impairments or visual disabilities where typing or manual navigation is challenging, Mareante offers a real-time hands-free voice interface.
  3. Spoken dialogue is accompanied by synchronized textual transcripts (FR-VC-03) to ensure accessibility for deaf or hard-of-hearing users.

Mareante relies on standard web technologies:

  • HTML5
  • WAI-ARIA 1.2
  • CSS3
  • JavaScript (ECMAScript 2022+)

The platform is designed to be compatible with:

  • Major modern web browsers (Chrome, Firefox, Safari, Edge);
  • Common assistive technologies (NVDA, JAWS, VoiceOver, Orca).
