/*
  SAMAN'S STUDY LOVE — "The Revision Notebook"
  ---------------------------------------------------------------------------
  THESIS: The study app IS Saman's own beautifully kept revision notebook.
    It refuses the pastel study-SaaS dashboard and the dark focus-timer app.
    Navigation is the notebook's tabbed edge; feedback is stationery
    (a highlighter pass, a tick, a red-pencil mark, a bookmark).
  OWN-WORLD: Cool blue-white paper (#F5F8FA), night-blue fountain ink (#26313F),
    one rose margin rule (#E4A3B8) down every page. Four highlighter washes —
    mint/red/lavender/sun — used ONLY with meaning. Solway slab headings,
    Atkinson Hyperlegible body, Kalam handwriting reserved for love alone.
  STORY: Saman opens the notebook to today's page, already warm with her name
    and the date; she generates a page of questions, works them with instant
    stationery feedback, and watches her weak pages grow fewer.
  FIRST VIEWPORT: Tabbed edge at left; today's page open — display greeting,
    the pressed-flower anniversary in the corner, "pick up where you left off"
    as the primary action, stat marks and a margin love note below.
  FORM: Grounded direction "The Revision Notebook" (#3 of the ordered list),
    seed 4c69fd8c. No skeuomorphic staging borrowed; the page itself is the
    stage. Romance lives in the margin, in one hand.
