-- 1. CORE LOGIC (Private internal function)
-- ==========================================
-- This replaces or wraps your original render logic.
-- It accepts raw strings instead of a MediaWiki frame object.
local function _render(month, day, year, height)
    -- -------------------------------------------------------------
    -- [PASTE YOUR EXISTING EXCERPT RENDER LOGIC HERE]
    --
    -- For example, fetching the page "Update:Month Day, Year",
    -- cropping it to the given height, processing tags, etc.

    -- (Mock placeholder returning a string; replace with your actual logic)

-- ==========================================
-- 2. OLD ENTRY POINT (For backwards compatibility)
