Paper-Inspired Theme Demo

Exploring ruled paper cards, sticky notes, tape overlays, wooden desk backgrounds, and manila folder containers for the Sundog visual overhaul.

1. Ruled Paper Cards

Cards styled as notebook paper with horizontal ruled lines and a left margin line. These mimic classic lined notebook pages.

Research Notes

The Sundog Project demonstrates that indirect measurement through photometric signals can provide sufficient information for navigation and control tasks.

This ruled paper effect uses CSS gradients to create horizontal lines that repeat at consistent intervals, creating the familiar notebook aesthetic.

Theorem Sketch

Given partial observability, an agent can still achieve alignment through careful measurement of indirect signals.

The left margin line (in red/pink) adds authenticity to the notebook paper metaphor.

Implementation Detail

CSS class: .sd-paper-card

Uses linear-gradient for ruled lines and background-size to control line spacing (1.5rem default).

2. Sticky Note Sections

Post-it style notes with subtle rotation at rest and enhanced tilt on hover. Available in multiple pastel colors.

Yellow Sticky Notes (Default)

Quick reminder: Update the documentation to reflect the new theme patterns.

Sticky-note color tokens remain available as accents under Option C; text inherits the body sans stack.

Color Variants

Pink sticky note for urgent items or special emphasis.

Blue sticky note for informational content or calm reminders.

Green sticky note for success states or positive feedback.

Hover over any sticky note to see the enhanced tilt and shadow effect!

3. Tape Overlays

Semi-transparent tape effects that can "fasten" cards to the page. These decorative elements add tactile realism.

Card with Center Tape

This card has a tape overlay positioned at the top center, as if it were fastened to a surface.

The tape has a subtle texture and frosted glass appearance with realistic shadows.

Left Tape Variant

Tape positioned at the top-left corner with a different rotation angle.

Right Tape Variant

Tape positioned at the top-right corner for asymmetric visual interest.

4. Wooden Desk Background

A dark wood grain background that evokes a workspace surface. Apply data-theme="desk" to body or use .sd-desk-bg class.

Paper on Desk

This paper card sits on a wooden desk background, creating a realistic workspace aesthetic.

The wood grain texture is created entirely with CSS gradients—no images required.

5. Manila Folder / Clipboard Containers

Tan/cream containers styled as manila folders or clipboards, perfect for navigation or content areas.

Standard Manila Container

This container has a manila folder appearance with a subtle paper texture and realistic edge shadows.

The tan/cream color palette evokes traditional office filing systems.

Manila Container with Tab

Add the .with-tab modifier class to show a folder tab at the top.

This variant is ideal for sections that should appear as distinct folders or categories.

6. Combined Effects

Demonstrating multiple paper-inspired effects working together in harmony.

Research Project Folder

Experiment Log

This paper card includes a tape overlay, creating a layered, realistic effect.

The combination of ruled paper, tape fastening, and folder container creates a cohesive analog workspace aesthetic.

Remember to run Phase 6 baselines!

Check three-body integration tests.

All these effects work together to create a tactile, paper-based interface that maintains the scientific credibility of the Sundog brand.

7. Typography Hierarchy

The paper-inspired theme introduces three distinct typography voices:

Display Serif

Used for major titles and prestigious headings. Georgia and Times New Roman provide classical authority.

Console Monospace

Used for technical content, data labels, and code snippets. Maintains scientific credibility with clean monospace rendering.

Handwritten Casual — Deferred

Reserved for an Option-A or Option-D direction. Removed from the live token roster on 2026-05-08; see UI_UX_THEME_FOUNDATION.md.

8. Usage Guidelines

When to Use Paper-Inspired Effects

✓ DO: Use ruled paper for research notes, evidence panels, and content cards

✓ DO: Use sticky notes for highlights, reminders, and informal asides

✓ DO: Use manila containers for navigation areas and section groupings

Accessibility Considerations

• All paper effects degrade gracefully on older browsers

• Handwritten fonts are kept at minimum 16px (1rem) for readability

prefers-reduced-motion removes tilt animations

• WCAG AA contrast ratios maintained throughout (4.5:1 for body text)

• Focus indicators remain visible on all interactive elements
