/* ============ Post / Comment / Reply Emoji Reactions ============
   Layout requirements (per spec):
     • The reaction cluster grows from the BOTTOM-RIGHT corner.
     • With 1 emoji type, the pill sits in the bottom-right.
     • Adding more pills extends LEFTWARD on the same row.
     • When the row fills, new pills wrap UPWARD onto a row above —
       still anchored to the right.

   Achieved with a single flex container:
     flex-direction: row-reverse  → first DOM child renders at the right
     flex-wrap:     wrap-reverse  → overflow rows wrap upward
     justify-content: flex-start  → items pack against the (now-right) start
     align-content:   flex-start  → wrapped rows pack against the (now-bottom) start

   Pills are sorted DESC by count in JS, so the most-popular emoji
   ends up first in DOM order → rightmost on screen. The "+ react"
   button is rendered LAST in DOM → leftmost in the cluster. */
