Review Summary

I am requesting changes because there are still a couple of requirement-level issues that block full acceptance. First, the task explicitly requires styles to be written in src/styles/main.scss, but your code uses src/styles/index.scss and links to styles/index.scss from src/index.html; this violates the technical constraint and needs to be fixed by moving the styles into main.scss and updating the <link> href accordingly. Second, in src/index.html the calendar element has both calendar--start-sun and calendar--start-day-sun classes, while only the calendar--start-day-* modifiers are defined in your SCSS; the extra calendar--start-sun is unused and conflicts with the specified modifier naming [CHECKLIST ITEM #1 and #3], so it should be removed.

To address these blockers: 1) create or use src/styles/main.scss, move all your current SCSS from index.scss into it, and change the HTML <link rel="stylesheet" href="styles/index.scss"> to href="styles/main.scss"; 2) in src/index.html, edit the main (calendar) tag so its class attribute becomes something like class="calendar calendar--start-day-sun calendar--month-length-31", removing calendar--start-sun. Apart from these issues, your layout, hover behavior, use of SCSS directives, and BEM structure for elements look solid and are very close to the intended solution. Once you fix the stylesheet path/name and the stray modifier class, your solution should meet all core requirements and pass the checklist.
