Elevation and shadows: cards, modals, sticky header

[1nonlypiece]

Description

Apply design-system/tokens/shadows.json levels to vault cards, modals, and sticky elements.

Requirements and context

• No shadow stacking bugs on mobile

• Dark mode shadow tuning

• Deliverables must be reviewable in Figma (or equivalent) and traceable to Disciplr-Frontend / design-system/

• Should respect WCAG 2.1 AA targets for default theme unless explicitly scoped otherwise

Suggested execution

1. Fork Disciplr-Org/Disciplr-Frontend and branch: git checkout -b design/shadows-elevation
2. Produce frames + specs (spacing, type, color, motion) before deep UI code changes
3. Share a short Loom or PR description with before/after for stakeholder review

Design deliverables

• Elevation scale diagram
• Token usage notes

Handoff

• Link Figma file + node IDs in the PR (or attach exports if Figma is not used)
• Note any updates needed in design-system/tokens/*.json

Test and review

1. Run a design critique (internal) with eng + design
2. Validate keyboard + screen reader on affected flows (smoke level)
3. Capture screenshots for light mode; note dark mode gaps if applicable
