Accessibility & Sensory Standards
Every learner here is neurodivergent, so accessibility isn't a checklist — it's the point. These are the rules every screen follows, and the accommodations every learner can turn on for themselves.
Contrast that clears WCAG AA
Body text hits 4.5:1; large text and UI hit 3:1 — verified, never guessed.
Light-sensitive and low-vision learners read without strain.
Type the reader controls
16px minimum, scalable to 150%, adjustable line spacing, and an optional readable font.
Dyslexic and ADHD readers set what actually works for them.
Reachable by touch & key
44×44px minimum targets, a visible 4px focus ring on every control, logical tab order, skip links.
Full keyboard and motor-friendly operation, no mouse required.
Calm, optional motion
Only 0.2–0.35s fades; honors reduce-motion; no autoplay, flashing, or parallax.
Protects against overstimulation and seizure triggers.
Meaning beyond color
Status always pairs color with an icon and a word — never color on its own.
Clear for color-blind learners; removes ambiguity for everyone.
Built to be heard
Semantic HTML, ARIA labels, alt text, live-region announcements, and read-aloud on every lesson.
Non-readers and screen-reader users get the whole lesson.

Sensory & accessibility controls
Every learner can shape the interface to their own comfort. Adjust the controls — the sample lesson responds instantly, and every change is announced for screen readers.
A fraction shows part of a whole
The bottom number tells how many equal parts there are. The top number tells how many you have.
Which fraction is one half?
The same adaptation engine ships in the product — settings persist per learner.
