Low Risk
CSS-only calendar layout tweaks with no logic, data, or security impact.

Overview
The desktop calendar grid now shows clearer vertical separators between day columns.

Weekday header cells get a right border on every column except the last, using border-r-neutral-200 so dividers align with the header row’s existing bottom border. Day cells use the same stronger right border while keeping the lighter bottom border (border-b-neutral-100), so column lines read consistently from the header through the grid.

Last column border inconsistency between header and cells

Low Severity

The header in calendar-view.tsx conditionally applies border-r only to columns before the last (i < visibleHeaders.length - 1), but DayCell unconditionally applies border-r border-r-neutral-200 to every cell including those in the last column. This creates a visible vertical line on the right edge of the last column's day cells with no matching border in the header above, producing a visual misalignment between headers and body.
