The stagger delay variables defined in this file are not being used. In animations.css, the animation delays are hardcoded (0.1s, 0.15s, 0.2s, etc.) instead of using these CSS variables. Consider either removing these unused variables or updating the animation delays in animations.css to use them (e.g., animation-delay: var(--stagger-1);). This would improve maintainability by centralizing the delay values.

There's a discrepancy in the asymmetrical grid ratio. This PR implements 0.9fr 1fr, but the referenced PR #6 (mentioned in the description) states it uses 0.85fr : 1fr. Please verify which ratio is intended and ensure consistency between the implementations.

The cubic-bezier timing function is hardcoded here but a CSS variable --ease-out-expo is defined in variables.css with the same value. Consider using var(--ease-out-expo) instead for consistency and maintainability, as is done in other animation rules (lines 63, 68, 87, 92).

Suggested change

P1 Badge Keep form blocks visible after entry animation

Because main.css imports utilities before components, the later .form-block rule in components/forms.css overrides the animation here and drops the forwards fill mode. With opacity: 0 still coming from this rule, once the entry animation finishes (normal motion, non-reduced), the blocks revert to opacity 0 and effectively disappear. Consider removing the base opacity or ensuring the final animation rule keeps forwards/sets opacity: 1.

The animation delays are hardcoded here, but CSS variables for stagger delays (--stagger-1 through --stagger-6) are defined in variables.css. Consider using these variables instead to improve maintainability. For example: animation-delay: var(--stagger-1); for the first child, animation-delay: var(--stagger-2); for the second, etc.

The focusRingPulse animation sets box-shadow values that will override the static box-shadow defined in forms.css line 146 (.form-group input:focus has box-shadow: 0 0 0 3px rgba(99, 102, 241, 0.12);). The animation starts with box-shadow: 0 0 0 0 rgba(var(--primary-rgb), 0.4) and ends with box-shadow: 0 0 0 3px rgba(var(--primary-rgb), 0.15). This means after the animation completes, the box-shadow will be 0 0 0 3px rgba(99, 102, 241, 0.15) instead of the expected 0 0 0 3px rgba(99, 102, 241, 0.12) from the :focus rule. Consider adjusting the animation's final state to match the static focus style, or adjust the static style to use the animation's end state.

The reduced motion media query only explicitly sets opacity for .form-block elements, but other animated elements (.form-section, .invoice-section, .invoice-placeholder, .item-row, .history-panel) also start with opacity: 0 in their animations. When animations are disabled with animation-duration: 0.01ms, these elements might flash briefly at opacity 0 or may have visibility issues. Consider adding explicit opacity rules for all animated elements within the reduced motion media query to ensure they're fully visible, similar to what's done for .form-block.
