# Lesson House asset provenance

Created and reviewed: 2026-10-03.

All HTML, CSS, JavaScript, instructional sample copy, the house-and-notebook mark, window/plant/sunlight illustration, pencil-like annotation strokes, ruled paper, field notebook, coral permission note, and classroom poster are original MRHTML materials. Copyright 2026 MRHTML. Covered by the accompanying MIT license.

No stock photography, Unsplash images, third-party artwork, icon sets, logos, remote fonts, audio, video, analytics, or external dependencies are included. The visual artwork is authored inline SVG, HTML, and CSS. The browser draws geometric shapes and ordinary typographic characters.

Font stacks use locally installed Arial/Helvetica, Georgia/Times New Roman, and Courier New/monospace fallbacks. No font files are distributed or fetched.

Lesson House is an original fictional course-site concept. The sample exercises do not imply an operating school, instructor qualification, enrollment offer, testimonial, certificate, or endorsement.

Because no external assets are included, there are no third-party asset source pages, photographers, retrieval licenses, or network resources to verify.
