A refined reader experience for long-form text with an emphasis on active reading and personal comfort. Users can color-code important fragments in one tap, then fine-tune typography from a compact settings sheet without losing context. The UI stays lightweight (chapter header, page counter, subtle controls) so content remains front-and-center while still offering the power features heavy readers expect: multi-color highlights, adjustable line height and margins, justification, and quick theme switching (Light / Sepia / Dark / Black). Ideal for books, stories, knowledge bases, and training materials on phones and small tablets.

Functionality

• One-tap highlights: Long-press to select, then assign a color from a palette; change or clear in place.

• Typography controls: A-/A+ font size, line spacing and margins sliders, justify toggle.

• Themes: Instant Light / Sepia / Dark / Black for comfort day or night.

• Context preserved: Settings open as a bottom sheet over the current page; no view changes or jumps.

• Reading context: Chapter title + page progress indicator (e.g., 5/34).

• Smooth paging: Swipe/scroll between pages; selection mode respects gestures to avoid accidental highlights.

• Stateful session: Highlights and reading position are preserved between sessions.

• Accessible by design: Large sizes supported; high-contrast themes; screen-reader friendly text layout.

Use cases

• Education & study: Color-coded highlights for quotes, terms, and exam prep.

• Corporate learning: Onboarding guides, SOPs, and field manuals with persistent notes.

• Personal reading: Novels and essays with night mode and comfortable spacing.

• Knowledge bases: Internal docs where quick annotation and recall matter.

• Research & reviews: Mark passages and return to them during editing or peer review.
