Feature Sunset Changelog Block for React

Edit FEATURES at the top of the file. A feature has a name, an area, four days in the order of the phases (as ISO dates), the affected sentence and the replacement. The phase it has reached comes from comparing its days with AS_OF, so the meter, the word and the Done, Next and Later marks are never typed by hand.

No. A copy of every closed row sits, unseen and inert, in the same grid cell as the visible list, so the block keeps the height of the full list whichever area is chosen. Opening a row is yours to choose and does grow the block, as any disclosure does. Pressing the chosen filter again does nothing, so the list is never empty.

No. A closed row's content is inert, so its phases are out of the tab order on every base.

Four squares, one for each phase, filled as the feature reaches them, with the phase's name in words beside them and a visually hidden "Phase 2 of 4". It reads the same in greyscale and to a screen reader.

On a phone each closed row stacks its name, its phase and its removal day, and an opened row lists its four phases one per line. In a right-to-left layout the text mirrors, while the squares and dates keep their reading order.

The header and the list fade up once on load, and a row's chevron turns as it opens; reduced motion turns that off. Changing the filter swaps the rows at once.
