Update TreeFlower concept designs:
    
        - Stop using Serif style on artistic motif concept phrase, and
          copyright bottom note. Start using Sans style instead.
    
        - Remove artistic motif concept phrase from A4-landscape poster
          design to bring attention down to copyright, description and
          license information area.
    
        - Update copyright note at motif poster design. Add description
          line about what TreeFlower is, between copyright note and
          license note. Description line introduce license line, in a way
          we could say clearly what we are releasing exactly.
    
        - Inside A4-portrait, and D6-portrait poster desings, the artistic
          motif phrase typography was reduced to improve readability.
    
        - Update copyright note to stop using 'YEAR1-YEAR2' format. Use
          'YEAR1, YEAR2' format instead.
    
        - Update copyright note to add `All rights reserved.' after name.
    
        - Copyright information (i.e., copyright line, description line,
          and license line) are now into one common multiline text box
          with 130% of text-height.
