/* Rivera Brazil · components.css
   Every component (06-DESIGN §10, §11). Page CSS only composes these; it never creates new ones.
   Order: ink · header · button · doors · notes · grid · opening · line · divider · proc · bench (sheet, lanes,
   player, turns, format panel, tapes, states) · credits · audience doors · folder + report · mini-form ·
   colophon · contact fields · study ruler · glossary · crosstalk line · slips · committee sheet · navy plate
   (promoted from page CSS in round 1; round 2 dropped the constellation, see 10-revisao.md).
   Breakpoints, mobile first: sm 37.5em · md 56.25em · lg 64em · xl 75em.
   State rules for the bench live inside @supports selector(:has(*)); the base CSS draws "what you receive". */
